Queries regarding heat pump.

[driftking]

Dear friends, I have following queries.
1. Can we get temperature of 80 deg. in Air source heat pump?

2. Can we pass furnace oil instead of water, so it can be used as a preheating of furnace oil applications?

Yes & yes (needs careful design for the condenser - secondary loop would be safer though. Then some dT lift is lost due HE).

What COP do you require? This may end up making nonsense of the prospective energy savings.

@ desA

How would you specify the heat exchanger for the furnace oil, with the specific density of oil being different to that of a glycol water mix?

[desA]

Very carefully.

lol, thanks for the input desA, but say if I specifically wanted to size one up, what variables would I have to take into account?
