Heating FAQ's (Frequently Asked Questions)
Q) Leaking pipe :- Why is the pipe attached to my boiler leaking ?
A) The pipe your referring to is most likely attached to the pressure relief valve, and is leaking because it has reached it's blow-off point (pressure over 30psi). This is a safety device which is designed to keep the boiler from reaching pressures above 30psi. High pressure combined with high temperatures will result in an explosion, at this point I’d recommend shutting off the water & power to your boiler and giving us a call.
Q) Boiler & Furnace maintenance :- How often should I have my boiler / furnace cleaned ?
A) Gas fired furnaces & boilers should be serviced and cleaned every four to five years and oil fired boilers should be serviced and cleaned every second year. All boilers should have mechanical parts such as pressure regulator, backflow-preventor, pressure relief valve, and expansion tank replaced every ten to twelve years.
Furnaces and air handlers with evaporator coils should be cleaned and washed down every three to five years, same goes for the outdoor condenser. Evaporator coils and condensers get plugged-up with pollen and small particles of dust, which reduce the efficiency and effective transfer of hot or cool air.
Q) Adding AC :- Is it possible to add AC (cool air) to my heating furnace ?
A) Most furnaces can be retro-fitted with a cased or uncased evaporator coil depending on the existing furnace age ; blower motor and controls.
Have your HVAC specialist assess the system first.
Q) Heat Pumps :- Will a heat pump work in New England winters ?
A) Heat pump technology has come a long way. Many mini-split systems will now operate effectively under harsh winter conditions (3F-20F) whereas a whole house split systems may not be as effective. Many variables should be considered before deciding to install a 100% heat pump system over a mixed energy system such as a gas/electric system where the heat pump would be used for a short period before freezing temperatures arrive and switch over to the gas or electric coil portion during freezing temperatures.
Q) Radiant heat:- I want to install radiant heat in my basement. Is this possible without having to rip-up the concrete floor ?
A) Any installation of radiant flooring which keeps the tubing off the concrete is recommended and preferred. Some of our best installations of radiant heat have been done in basements, using a floating floor system which acts as both a vapor barrier and an insulator, we install a slotted radiant track which provides even heat to the entire area. Below are some pictures of a section of radiant flooring in which antifreeze was needed (note the red color in the tubing) for a separate section of the heating system which was exposed to the elements on a four season deck.
Q) Frozen baseboard:- I have a section of baseboard in a four season porch which freezes up occasionally. How do I prevent this from happening ?
A) The first and most cost efficient way of keeping any part of your heating system from freezing would be to pump antifreeze (non toxic solution) into the heating system. With the exception of systems containing Aluminum, CPVC and Galvanized Steel. Most antifreeze solutions will even protect the metals in your heating system against corrosion and lubricate moving parts. Antifreeze solution should last up to 6-7 years depending on the size of your heating system, and should be checked every two to three years for high acidity (pH) levels. Whether you have freeze-up problems or a fully functional heating system that has never frozen up, I would recommend anti-freeze to all homeowners with radiant (hot water) heating systems. Since mechanical items such as circulators, gas valves, etc break down at the most inopportune times, anti-freeze is your insurance policy against high repair costs of burst, frozen piping & boilers.
The second solution to your problem is to create a seperate zone just for that four season room, by adding a switching relay to your boiler and rerouting the piping going to and coming from the radiators. This room can now be controlled by its own thermostat. Other solutions would include installing a jog/exercise relay on the heating loop to periodically keep water moving through the heating lines.
Q) Incentive Programs:- I'm thinking of replacing my old heating system / water heater, will I qualify for any rebates or incentives to install new equipment ?
A) Utility companies change, incentive / rebate programs frequently. Most providers will incentivize high efficient heating, hot water and A.C equipment. Please call your provider for more information or if located in Massachusetts, contact Mass Save at - http://www.masssave.com/residential/mass-energy-rebate.
