- John Siegnethaler and Michael Ridler are passionate about heat pumps and close friends. During a recent training session for engineers and contractors they took some time to discuss the features of this exciting new technology.
Eden Energy Equipment is the distributor for Enertech Air to Water products for Canada and has units in stock. We provide turn key design with in house technical and design support. Reach out to us to learn more. info@edenenergy.com
Does it have the ability to dump excess summer heat to a buffer tank - rather than just dumping it outside?
Whats the min turndown on that unit..................30%?
The unit is a digital scroll with a minimum rpm of approximately 1500 rpm and a max of roughly 7200rpm. With this you will see a flow rate of 3 gpm to 14 gpm or roughly 8000 btus to 60,000 btus depending on outdoor design conditions and load in the building.
The unit is capable of doing much lower ( think 800 btus ) but the equipment has a lot of logic built in to protect the unit from abuse and mistakes by the installer. When the unit fires up it will always ramp up to approximately 2400 rpm for about a minute to prevent oil pumping issues before it actually starts to modulate down to its minimum as it heats the home. This is why its important the system gets PIPED properly. The beauty of this unit is thanks to the packaged indoor unit they have eliminated 90% of the field issues we normally see.
If you need lower then the minimum firing it is easily achieved with zone synchronization to prevent small loads from beating up your heat pump. The key to any good hydronic heat pump install either air to water or water to water is a good installer who knows what they are doing and a distributor that can support them. Thanks for the great comment!
Why wouldn't you go with R290 since it's a monoblock and all the refrigerant is outside?
R290 is not currently an option in any air to water residential equipment in North America. R454 and R32 are very common. We agree R290 is a great solution when it comes.
