Hydronic Heat Pumps

Member Posts: 17
With the increased emphasis on CO2 working fluid A/C systems especially in automotive applications, do you think the wider working temperature range will provide capability for hydronic heat pump home heating systems?
Do you know of any hydronic heat pump home heating system currently available?

I am not sure what
you are asking in your fisrt question.
Yes to your secound. We have a very happy customer with a water to water heatpump. We heat with the floor and cool with a chilled coil airhandler.0 -

Hydronic Heat Pumps
What brand of equipment is it? My understanding is that due to the limited temperature range of heat pump working fluid the hydronic maximum temperature is only about 115 deg F.0 -
I use Heat Controller
The working fluid in a heat pump is a refrigerant. The upper limits of water leaving temperature is governed by the temperature of the water entering the machine. I could not find the installation manual on their web site so I would need to get one to give you real numbers.0 -
Does anyone make a water to water heat only heat pump? If so does it make it any cheaper?0 -
Bill are you asking about CO2 refrigerant being used in a heat pump application?0 -
Hydronic Heat Pumps
Yes, my understanding is that using CO2 as a refrigerant (R-744) the temperature range of operation is extended beyond typical refrigerants and it could be used with a hydronic or hot water system to get much higerer temperatures than typical (about 115 F).
CO2 is being used in automotive because green house gases are being phased out and that includes typical refrigerants. I would think it would be just a matter of time for it to be required in home A/C and heat pump applications?0
