Pitfalls:
You have a small space: heatpumps need airspace and it needs to circulate. An enclosed closet won’t work.
Your heater is outside: heatpumps pull air through and dust/cobweb buildup isn’t good.
You dont have electricity to the heater: heatpumps need a decent cuirruit size to run. Some can run off a small 120v circuit.
You didn’t size right: heatpumps can’t keep up with sustained demand usage. A larger tank offsets this.
You can keep your old system too though. Just put your hybrid before it and set your temps at like 125 for the heat pump and 120 for the boiler. Your boiler will rarely need to run unless you have sustained usage, a power failure, or it needs to bring temps up in the water it’s holding.























I haven’t seen a water heater with one though.
