Hi sirs
One two-storey seaside villa (250m2). Need comfort AC with hot water supply. The solutions may be as follows:
1) Air cooled heat pump + FCU +heat reclaim hot water parellel with solar water heater;
2) GSHP +cooling/heating panel ceiling + fresh air unit+hot water with reclaim heat and solar water heater or elctrical heater
3)Air cooled hp or GSHP with air duct + fresh air ventilator

etc.

How to determine which one is best? Based on the cost or the comfort level or other things?
pls advise

Hi Lc_shi

Dependent on average ambient air temp all year round I would consider the air sourced heat pump.
The instalation costs would be low and they are capable of delivering hot water to above 60degC and if you get the right type they will also deliver cooling for the air conditioning side.

It's good idea to use air heat pump and it can also supply hot water at the same time. But how about the hot water supply in winter time? Need extra capacity.
How do u think to use GSHP in villa? The initial cost may prevent customer to accept it

Maybe to use electrical water heater...,but GSHP is better solution for all year around. Installation cost is high but .....

I think you should offer both solution to your customer and with good explanation I believe they will accept GSHP. The price must not be the only merit

Maybe some other guys have some good experience how to convince the client to buy something better...
