Replace your KoolR Magnum: the Wine-R WR2500 guide
The Wine-R WR2500 is compatible with the standard KoolR Magnum wall opening. Through-the-wall format, dedicated 115V/15A circuit, and in standard installations no cutting or framing changes are typically required. Fit and sizing are confirmed by pre-validation on every US order. $2,450 USD, 2-year parts warranty, ships direct to the 48 contiguous US states.
US owners replacing a KoolR Magnum
US owners of a KoolR Magnum installation in a residential cellar between 50 and 700 cubic feet with glass walls or up to 900 cubic feet in fully enclosed cellars, R-20 minimum insulation, and an existing through-the-wall installation.
What fits and what carries over
The WR2500 fits the standard KoolR Magnum wall cutout of 15 3/4 inches wide by 9 3/4 inches high, up to 7 inches wall thickness. It matches the through-the-wall format and runs on a dedicated 115V/15A residential circuit. In standard KoolR Magnum installations, no cutting, framing, or electrical work is typically required. Site-specific factors may require adjustment and are confirmed during pre-validation.
The wall opening, framing, and outlet from your original KoolR install carry over to the WR2500. The most expensive part of the original installation stays paid for.
The WR2500 covers cellars up to 700 cubic feet with glass walls and up to 900 cubic feet in fully enclosed cellars. With R-20 minimum insulation, a typical Magnum installation fits within range. For cellars beyond standard capacity, submit your project details and we will come back with a recommendation within one business day.
When your through-the-wall cooling unit reaches end of service life
Through-the-wall cooling units are finite-life appliances. The compressor wears out first. On residential cellar units, the compressor typically begins to show trouble between year 8 and year 12. The signs are familiar: longer cycle times, temperature creeping above setpoint on hot days, more noise than the unit used to make, and eventually a hard failure.
Units installed during the 2010s are reaching that window now. When yours reaches that point, the practical question is what goes in its place. Owners face a binary choice: cut a new wall opening to fit a different unit, or find a drop-in replacement that fits the existing opening.
The WR2500 fits that second path. Its through-the-wall footprint matches one of the established residential cellar formats, which means an in-kind replacement preserves the most expensive part of the original install (the wall opening, framing, and electrical) for the customer.
KoolR Magnum stopped cooling: repair or replace?
When a through-the-wall cooling unit stops performing, owners generally weigh a repair against a replacement. Both can be reasonable. The right answer depends on the unit’s age, its warranty status, and a repair quote from a qualified technician. The information below is general guidance, not a diagnosis of any specific unit.
Symptoms worth investigating
A cellar that drifts warm, constant running without holding temperature, short cycling, ice on the coil, or increased noise are all worth investigating. Causes range from room conditions and airflow to component wear; a qualified technician can confirm which applies to your unit.
Weighing a repair
A repair addresses one component at a time. For units well out of warranty, some owners compare the repair quote against the cost of a new, warrantied unit. Repair can be the right choice, particularly for a recent unit or a minor fix. A written quote is the best basis for the comparison.
If you consider the WR2500
The WR2500 is compatible with the standard KoolR Magnum wall opening, so in many cases the existing opening can be reused. Compatibility of the opening is one part of the decision: cooling capacity must be validated against your cellar’s size and construction, and the WR2500 requires a condensate drain line. Pre-validation on every US order confirms fit and sizing before the unit ships.
Side by side: KoolR Magnum and the WR2500
Three measurements and three photos, every US order
Measure the existing wall opening at three points: width, height, and wall thickness. Take photos of three views: the cellar-side face, the warm-vent side, and the electrical outlet. Send the measurements and photos through the Compatibility check. Wine-R confirms fit before the unit ships. Pre-validation is required on every US order. The WR2500 fits the standard KoolR Magnum opening, but every install has site-specific factors (drywall depth, framing variations, conduit position) worth verifying once before committing.
What stays the same
The wall opening from your KoolR Magnum works for the WR2500. The width, height, and wall thickness range match. The framing around the opening, the drywall finish, and the trim do not need to change.
Electrical typically does not change. The WR2500 runs on a dedicated 115V/60Hz/15A circuit. A dedicated circuit is required: shared loads, extension cords, and switch-controlled outlets void warranty coverage. If your existing outlet shares a circuit with other loads, have an electrician add a dedicated circuit before installation.
The warm-side venting requirement stays. Through-the-wall units exhaust heat into the warm side of the wall (utility room, garage, mechanical closet) with adequate airflow. If your KoolR Magnum was venting properly, the WR2500 will too.
What changes
The fascia design is different. The WR2500 front face does not match the KoolR Magnum. If you built custom trim or a surround around the KoolR fascia, that trim probably will not align with the WR2500. Most installations are straightforward to retrim, or to leave with the manufacturer fascia.
The warranty and support relationship is different. The WR2500 ships with a 2-year limited parts warranty supported directly by the Wine-R North American service team. There is no dealer in between. When you call or email about a unit, you reach the people who built it. Replacement parts are stocked in North America and ship under the warranty terms when applicable.
The ordering process is different. Wine-R sells direct to consumers in the US through a secure checkout with sales tax calculated automatically per state. There are no dealers between you and the unit. The WR2500 ships direct to all 48 contiguous states, delivered in 5 to 8 business days.
Condensate management: what you need to add
The WR2500 produces condensation during normal cooling cycles. This is standard for through-the-wall wine cooling units in residential cellars. A condensate drain line is required for safe long-term operation.
Drainage options:
- Gravity drain to a nearby waste line, condensate pan, or floor drain (preferred)
- Condensate pump routing to the nearest drain (where gravity drainage is not possible)
If your KoolR Magnum installation included a drain line, verify it remains accessible, sloped correctly, and clear before installing the WR2500. If your KoolR Magnum did not include a drain line, plan and install one before commissioning the unit.
Drainage configuration, installation, and ongoing inspection are the responsibility of the customer or the installer. Wine-R does not warrant against water damage, mold, finish degradation, flooring damage, structural damage, or any property loss caused by drain line installation, slope, blockage, freezing, overflow, or drainage failure of any kind. Verify drainage capacity and route before installation. Inspect the drain line periodically as part of normal cellar maintenance.
Sizing check before you order
The WR2500 covers cellars up to 700 cubic feet with glass walls and up to 900 cubic feet in fully enclosed cellars, with R-20 minimum insulation. Larger cellars are reviewed case by case.
Glass exposure: glass roughly doubles the heat load per square foot compared to an insulated wall. A cellar with glass walls or a large glass door requires more capacity. The Wine-R WR2500 covers up to 700 cubic feet with glass walls. Submit your project details and we will come back with a recommendation within one business day.
Oversizing risk: oversizing a unit is sometimes assumed to be safer than undersizing, but it is in fact the same common cause of premature compressor failure in residential cellars. The unit cycles too long, the compressor wears faster, and the temperature inside the cellar swings more than the wine should see. The right size is what the calculator and our technical team confirm for your specific build, not a safety margin.
The BTU calculator factors in cubic footage, climate zone, glass exposure, and insulation. A few minutes there will tell you whether the WR2500 is right for your space.
Common questions about replacing a KoolR Magnum
Yes, in nearly all KoolR Magnum installations. The standard KoolR Magnum wall cutout is 15 3/4 inches wide by 9 3/4 inches high. The WR2500 fits this opening in standard installations. Send width, height, and wall thickness measurements plus photos through the Compatibility check before ordering. Wine-R confirms fit specifically for your opening before shipping.
In most cases, yes. The WR2500 runs on a dedicated 115V/60Hz/15A residential circuit. If your existing outlet is on a dedicated circuit and in working order, no electrical changes are typically required. A dedicated circuit is a warranty condition: shared loads, extension cords, and switch-controlled outlets void coverage.
Most US orders are delivered within 5 to 8 business days. The WR2500 ships direct to all 48 contiguous US states.
The WR2500 is comparable in operating sound to the KoolR Magnum. The compressor sits on the warm side of the wall, which keeps most of the noise out of the cellar space. Specific decibel levels depend on the install conditions on both sides of the wall.
The WR2500 covers cellars up to 700 cubic feet with glass walls and up to 900 cubic feet in fully enclosed installations. For larger cellars, submit your project details and our technical team will come back with a recommendation within one business day.
Through-the-wall replacement is DIY-feasible in straightforward installations where the existing wall opening, electrical outlet, and drainage are in good working condition. Where any of these require modification, addition, or verification, Wine-R recommends engaging an electrician, plumber, or general contractor familiar with cellar installations. Wine-R does not certify installers and does not assume responsibility for installation outcomes.
Every WR2500 comes with a 2-year parts warranty supported by the Wine-R North American service team. Full warranty terms and how to reach support are on the support page.
Wine-R currently ships within the 48 contiguous US states only. Alaska, Hawaii, and US territories are not in the current shipping zone. Contact the Wine-R team if you are in those regions and we will share timeline updates.
Some KoolR Magnum installations have site-specific factors: thick custom drywall, modified framing after years of use, or conduit that runs through the opening area. Send your measurements and photos through the Compatibility check. The Wine-R team reviews and confirms fit before the unit ships, on every order.
That decision depends on your unit’s warranty status, its age, and the repair quote from a qualified refrigeration technician, and it is entirely yours to make. If the unit is under warranty, warranty service is typically the first step. If you are exploring replacement, note that the WR2500 is compatible with the standard KoolR Magnum wall opening, but a compatible opening is only one part of the picture: cooling capacity must be validated against your cellar (our BTU Calculator and pre-validation cover this), and the WR2500 requires a condensate drain line. Every US order is pre-validated for fit and sizing before it ships, with no obligation at the review stage.
Symptoms owners commonly report on any through-the-wall cooling unit include a cellar that drifts warm, a unit that runs constantly without reaching temperature, frequent short cycling, ice on the coil, or a noticeable increase in noise. These symptoms can also be caused by room conditions, airflow, or installation factors rather than the unit itself. Only an inspection by a qualified refrigeration technician can identify the actual cause on your specific unit.
Yes. The WR2500 produces condensation as part of normal operation, which is standard for through-the-wall wine cooling. A condensate drain line is required. Gravity drainage to a nearby waste line is preferred; a condensate pump is acceptable where gravity drainage is not possible. Drainage configuration, installation, and inspection are the responsibility of the customer or the installer. Wine-R does not warrant against water damage or property loss from drainage installation, blockage, or failure of any kind.
