Gas Furnace with pumps?

Asked by New Homeowner In Ct, Fairfield, CT Sat Feb 4, 2012

We just bought a house and want to replace the gas furnace. My contractor is suggesting that instead of keeping the three switches we currently have for heating the three floors, we replace them with three pumps that individually pumps airs into the floors. What is the advantage of doing this? The cost is about $3,000 more to do this. Thanks.

Can you further explain your system?

I'm an agent, but also an HVAC designer (sorry to prove you wrong Mark about an agent not being an professional in this area, lol). What is confusing me is "pumps air" If your furnace is a forced air furnace that blows air through duct work you'd create multiple zones by adding control dampers to modulate air to different areas.

However, the discussion of pumps and switches makes me think that maybe this is a boiler system that is piping hot water for heating to radiators in the house. Maybe what you're referring to as switches are on/off valves. In that case, multiple pumps could make sense to better control hot water flow through the radiators.

Hi in Fairfield, CT. If you worked with a home inspector on your purchase, give them a phone call or email and ask them. Many home inspectors are happy to answer phone questions like this. Second choice is to contact a second contractor for their opinion. Real estate agents are good at basic information on homes, but any real estate agent who offers advice on your gas furnace is not a professional in this area and the answer you get will be worth exactly what you paid for it. You definitely need a professionals opinion. Good luck!

It sounds like he is recommending that you create separate zones for heating your home. If this is the case then the advantages would be that you would be able to set and control the temperature of each zone independently from the others, i. e. keep the bedrooms on a lower temperature during the day than at night because no one is using them. This set up will reduce your heating costs if used properly. It is also considered more desirable and adds value from a resale perspective.
