My use for your air to water heat pump products will be limited to DHW and the existing kitchen/bath radiant loop. That might extend to some kind of wall radiant emitters for the other two bathrooms depending on calculating the load and the availability of products matching the load. My needs most closely match the following configuration.
I will set up some monitoring on the existing radiant loop for temperature-in and temperature-out which combined with knowing the flow rate should give me the btu/hr load.
I am not looking for a "quick estimate". What I need from you is performance and engineering data and pricing on all of listed components.
The rest of the house will likely replace 180 degree baseboard emitters with air to air heat pumps connected to some combination of wall units and air handlers.
29 years ago this was a carefully designed system which heats a 2,700 sf house with high ceilings and lots of windows for ~$1,500/yr @ $2.33/therm. I even got John Siegenthaler to weigh in with some invaluable advice.
With electricity here @ $0.27/kwh and natural gas @ .07/kwh it will be a big challenge to design a replacement system. Whatever it is will have to spend most of its time in the operating range that gives you a COP of ~4 or else the operating cost penalty will be too great.

Currently I have a 27 year old radiant floor system for the kitchen (200sf) and bath (50sf). It is pex in a thin slab under ceramic tile over an insulated joist/plywood floor. It runs continuously in the heating season on a loop off of a gas boiler that injects a bit of 100 degree water whenever the boiler is calling for either a baseboard zone or DHW.
The boiler is about ready to be replaced and I am exploring the feasibility of a design for both DHW the radiant loop to be powered by a heat pump or heat pump hot water heater. What do you suggest?

problem: tstat lights were on but zone valve lights were off. End switch was not being activated for LR and TV (intermittent)
- replaced LR zone valve with new, voltage between terminal 1 and 3 was low
- replaced TV zone valve with clip salvage, voltage between terminal 1 and 3 was low
- ordered spare from ebay. Still have one clip salvage 2nd shelf near boiler. Replaced valves are on top shelf, have tape folded back to indicate they were replaced.

I am interested in Arctic Heat Pump 035ZA/BE – 29,000 BTU for use in a domestic HW + radiant application. Could you send me submittal sheets and any other details on
Arctic Air to Water Heat Pumps
Domestic Hot Water The AltSource tank is equipped with an optional internal Heat Exchanger (HX) for domestic hot water production. This consists of 200 feet of 1/2” copper piping. Based on 120°F water tank temperatures this 200 ft of ½” OD cooper pipe, 26.2 sq/ft surface area and has a volume of 1.5 total gallons.
Because the efficiency of the heat pump is better at lower water temperatures, we recommend using the internal domestic hot water coil in a pre-heat arrangement. In this diagram the cold water enters the coil from the bottom and exists at about 95% of the tank setting temperature. Following this the warm water then goes to the primary tank or an on-demand water tank where it is topped up a few degrees to reach 120°F or more depending on the application. When sizing a heat pump with domestic hot water load please add about 10,000 BTU per person to the daily load. So, a house with 4 persons would need an extra 40,000 BTU per day. On an hourly bases this would be 1,667 BTU/hour over 24 hours.
What is a flow rate and what should I ask for? Consider how many of these needs you may have simultaneously to determine the maximum flow rate you require. For a home with 1 bathroom, we recommend 6-7 GPM; 2 bathrooms, 8 – 9 GPM; and 3+ bathrooms, 9-11 GPM. What is a flow rate and what should I ask for?
