Can I install a heat pump condenser instead of a straight cooling condenser on my hydro air system even though I plan to have oil heat? What is the downside?
It is a good idea to install a moderately more expensive heat pump condenser instead of a standard cooling condenser, as long as you plan to add a temperature control to switch modes in clod weather. Your heat pump will probably more efficient when outside temperatures are above 45 degrees. Your boiler will be sized for worst condition, and the heat pump will prevent it from firing at full capacity when it is not needed.
