FAQs
What is the difference between high efficiency boilers and standard boilers?
High efficiency boilers generally have efficiency ratings over 90%, making them Energy Star approved. These boilers are often modulating and condensing boilers. The modulation feature allows them to operate at different BTU levels depending upon the amount of heat that is required at a given time (as opposed to a traditional boiler that fires at 100% even if only a small amount of heat is required). The condensing property refers to the ability to convert the condensed liquid that is produced by the boiler into energy. By doing so the boiler wastes less energy and is therefore more energy efficient.
How can I tell how many BTUs the boiler I buy needs to have?
For replacement boilers, if your previous boiler was sufficient and worked well you can simply replace the existing boiler with a new one that has the same BTU capacity. For boilers that are being installed in new residences you will need to find the BTU requirements by doing a heat loss of your given space. The heat loss will depend on insulation of walls and ceiling, window type and frequency, outdoor temperature, and several other factors. You can click the Rule of Thumb Guide to get a general idea of what you will need, but you should get a detailed heat loss report to know for sure.
Which are your best selling brands of boilers?
The top selling brands of boilers are Weil-Mclain and Burnham. However, we have recently begun to sell a large number of the Triangle Tube Solo Boilers.
What is the shipping process if I order a boiler from you?
Boilers ship via freight shipping companies, such as Yellow and UPS Freight. When the order ships, we will provide you with the carrier name and tracking number. The boiler will be shipped to your curb. If you need a lift gate on the truck please call to let us know. In general, the freight company will call you to set up a delivery time. If you need a specific delivery time, you may want to call the delivery company once the order ships.
Do you honor the warranties on these boilers?
SupplyHouse.com honors all manufacturer warranties. If there is any manufacturer defect with the boiler we will replace it upon return, or issue you a credit for the boiler.

More About Boilers
The Industry's Best Residential Boilers
As a heating professional, you know the boiler is the most important piece of equipment in any residential heating system. In addition to keeping your client’s home at the ideal temperature, the right boiler will provide it with reliable heating, consistently and affordably for years into the future. SupplyHouse.com has all the best electric, oil and gas boilers for sale to suit unique space requirements, budgets and needs of any residential customer. And with free shipping on orders over $99 plus personalized customer service, we’d make great partners!

SupplyHouse.com is your resource for electric, propane, oil and natural gas boilers. Equip your clients with the very best and most efficient options by Burnham, Weil-McLain, Slant/Fin, Lochinvar, New Yorker, AO Smith and more. We have one of the industry’s best selections of high-efficiency gas boilers, which are quickly becoming the standard in both boiler replacements and new construction. These cutting-edge models use a gas-fired condensing system to heat your client’s home more efficiently, effectively lowering their utility bills and the home’s carbon footprint. These boilers can bring an Annual Fuel Utilization Efficiency (AFUE) rating of as high as 98 percent!

Boilers for Every Unique Job
In addition to efficient gas boilers, we also offer a wide variety of standard gas boilers which will still bring excellent savings and efficiency improvements when replacing old, low-efficiency boilers. Even standard mid-efficiency options can offer an AFUE rating of up to 83 percent, which makes them an economical choice for replacement applications. We also have an impressive selection of oil boilers and electric and wood boilers for your specialty jobs. Oil boilers are commonly used in properties with fuel oil tanks, whereas wood can be used in off-grid areas or when oil and gas options are prohibitively expensive.

Remember, if you aren’t sure which option is best for your client or job, you can always get in touch with us for expert advice.
