Heat Pump Management Tips for Cold Weather

 

Managing Mitsubishi Heat Pumps In Very Cold Weather

Mitsubishi Heat Pump Installation

With the arrival of below zero temperatures in our area, homeowners are asking what they can do to make sure they are getting the most from their heat pumps to keep their homes warm.

Even cold air contains some heat and with Mitsubishi’s renewable heat pump technology, this heat can be captured even when temps fall well below ZERO. For homeowners who have made aggressive energy improvements to their homes and installed heat pumps in locations intended to cover the whole home’s heating needs, your heat pump can keep working to keep you cozy warm.

As these extremely cold temperatures are forecasted to remain in our area for about another week, we wanted to take this time to remind you of a few tips to get you through this cold snap. Please keep in mind these tips are intended for people operating a zero energy home without supplemental heating options. If you have a supplemental heat source, you may want to use that.

Mitsubishi Heat Pump Tips

1. Turn the heat pump temperature up.
76 degree F is not too warm!  Remember, you are trying to heat the whole house from one location.  You do have to overheat the room(s) with the heat pump in order to make enough heat for the rest of the house.  The colder it is outside the bigger the temperature difference will be between the core of the house (with the heat pump) and the rooms (without the heat pumps).

 

2. Manually turn the fan speed to high.
It is likely that the heat pump will never kick into high fan speed on its own – it’s just the way the programming is set.  To get maximum heat out of the heat pump, move maximum air through the heat pump head.  It’s noisier so you may wish to only turn the fan speed up when you leave the room.

 

3. Do not turn the temperature down in order to save energy.You need the heat pump to give you everything it’s got, and that includes every minute of the day.  At these temperatures the heat pump capacity is noticeably lower.  Don’t restrict your heating to just part of the day, because there won’t be enough hours in the day to deliver the heat your house needs.  Keep the temperature at or above your comfort temperature all the time.

 

4. No need for extra ventilation.
You’re getting extra natural infiltration when it’s this cold (just due to the difference in buoyancy between the inside air and outside air), so you probably don’t need to add extra ventilation for fresh air.  If you typically leave a window cracked, close it.  If you have a ventilation system, put it on low speed or off for a day or two.

 

If you have a heat pump water heater, we recommend you use the electric resistance mode.  Remember, a heat pump water heater is an air conditioner in your basement.  Usually, the house can handle that extra bit of cooling, but when it is extremely cold outside, you want every Btu of heat to be available for your comfort.  The water heater can get its own heat from electric resistance without impacting the air temperature of the house.  Keep it in resistance mode until it stops impacting your comfort.  Just because the basement is cold doesn’t mean your comfort is impacted.  However, if the water heater actually makes your living spaces uncomfortable leave it in resistance mode.  At the latest turn, it back to heat pump mode April 1st.  Some years you may never need to put it in resistance mode.
