"I waited to send this review to make sure we were 100% satisfied with JDJ. Andy James of JDJ worked with us closely on our project to convert an oil burning boiler providing radiator heat and hot water over to a Natural Gas fired furnace - installed with regular duct work, an electric water heater and Central Air Conditioning. He also arranged to have our left over oil donated, old boiler and oil tank removed with no problems! We are warm in winter and cool in summer and very happy."

Install Boiler FAQs, answered by experts

A common HVAC rule is that for every 500 to 600 square feet of living space, you need 1 ton of heating or cooling capacity. Now that you know this common rule, you also need to know that it isn’t very accurate, and a dedicated pro wouldn’t use it for your home. If you talk to a pro who won’t or can’t perform a proper Manual J calculation, consider hiring someone more thorough.

Some high-quality steam boilers come with 10-year warranties, but a well-installed, properly maintained model can last at least 20 to 25 years. Learning how to clean a boiler, getting an annual professional service, and keeping up with maintenance and repairs on your heating system are all important for getting the most out of your model. 

If you go to turn it counterclockwise and it won’t turn anymore, it’s open. Like most other valves, you should be able to turn a radiator valve counterclockwise (to the left) to open it and clockwise (right) to close it. To close a radiator valve, turn it clockwise until you meet some resistance and can’t turn anymore, but do so carefully to avoid breaking the valve.

Coolant and antifreeze are technically not the same thing. The difference between the two is the ratio of water to other chemicals. True antifreeze is mainly made up of either ethylene glycol or propylene glycol, while coolant comprises one part antifreeze and one part water. However, the terms coolant and antifreeze are often used interchangeably, even by pros.

If you hear your radiator clanking even when it’s turned off, it’s typically because there’s trapped water or air in the system, causing a pressure buildup. When you hear significant clanking, popping, crackling, or banging in a radiator that’s turned off, you’ll want to bleed the pipes or call in an HVAC specialist to deal with the problem (and prevent it from happening in the future).
