Does anyone use a Gyser heat pump with a regular heat pump for their house heat? I was wondering how it heats your water? Do you have enouph hot water? We are going to get a climate master heat pump for our house. Im thinking a gyser heat pump for our hot water. Im wondering if its going to pull alot of heat out to work and cool the room even more? Were thinking of doing a 80 gal hot water tank with it but I dont know if an on demand tankless water heater would be better (cost wise) Thoughts? thanks in advance.
