40 is plenty cold. Lower setpoint temperature means lower heat pump efficiency but more cooling to your house via the air handler. What are...
The best $50 you’ll ever spend [ATTACH]
Wow, 14 tons heating load. What are you planning on building ? Given the millions your project is going to cost, I would recommend to take a...
Bear with me. Say your ground loop pump delivers fluid to the heat pump at a constant 5 gallons per minute. That five gallons per minutes goes...
Maybe your problem heat pump is not getting sufficient flow rate ? And it only manifests itself as an issue when you have high heat requirements...
You are a bit over the top on backup scenarios. A water source heat pump in your area will work extremely well and as long as your heat pump and...
Sounds great, simple is better as long as it works ! I wouldn’t rule out using what you have already installed for cooling. You would only need...
Sure it’s possible and very doable. You just need a buffer tank (assume you already have) plus a discrete distribution pump feeding an air...
I have the 120 gallon Caleffi NAS20123 with electrical backup for hot water generation using a water to water heat pump. @docjenser , who posts...
I have two Terra Therm air handlers hooked up to a 5 ton water to water heat pump and they work great. I particularly appreciate that the entire...
You are looking at a $100K plus investment decision on a HVAC system for new build construction. Really you owe it to yourself to study and...
@gsmith22 is using what he has to produce hot water, nothing wrong with the strategy. He has a high tech WF 7 heat pump, which is a water to air...
My two cents worth - you get what you pay for of course ! Huge project, couple of million and years of construction time, you will want to hire a...
You should be using purified water in your closed loop to avoid any source of bacterial growth. Borrow 55 gallon drums or other sanitized...
The ‘second stage’ heat pump would presumably heat the DHW to elevate the tank temperature from say 120 F to 140F and ride piggyback on the...
