At 14,000 btus, It is in easy range of even a small a mini-split. While the output is dumped into a large room, usually the living/dining, its heat or cool will in reasonable time get to the rest of the house.

Is the heat pump water heater used w radiant floor heating to also heat the house? If so, 4338W/240v=18A. Pretty good for dhw and house heating. If we convert 4338W to btuh, it's about 14,000 btuh and at 1800 sqft, about 8 btuh/sqft, again a good number for a heating load. Going to net zero carbon, a heat pump water heater in a garage or cellar might work well for a tight, well-insulated house. regards, bill Bill Hennessy Berks Solar, LLC 371 Centennial Rd Mertztown, PA 19539 o 610 682 4300 c 484 560 4666 NABCEP certified installer PA contractor #44411 www.berkssolar.com From: Dana <d...@solarwork.com> To: 'RE-wrenches' <re-wrenches@lists.re-wrenches.org> Sent: Tuesday, May 26, 2015 10:53 AM Subject: Re: [RE-wrenches] Water Heater Heat Pumps What kind of power draw do you see on this unit? & what kind of duty cycle do you see for 2 people or 4 people? I amp clamped a 1800 sqft house heat pump for DHW & house heat in full power and measured 4338 watts & have a rough time recommending heat pumps for off grid. ---------------------------------------------------------------------------- Dana Orzel Great Solar Works, Inc - NABCEP # 051112-136 E - d...@solarwork.com - Web - solarwork.com O - 970.626.5253 C - 208.721.7003 "Responsible Technologies for Responsible People since 1988" Please consider the environment before printing this email. -----Original Message----- From: RE-wrenches [mailto:re-wrenches-boun...@lists.re-wrenches.org] On Behalf Of Tom Lane Sent: Monday, May 25, 2015 3:59 PM To: re-wrenches@lists.re-wrenches.org Subject: [RE-wrenches] Water Heater Heat Pumps Water heater heat pumps make excellent sense in a garage in HOT HUMID SOUTHERN CLIMATES and about 700 square feet of garage space is necessary AND you must run a condensate line like an air conditioner . DO NOT PUT THEM IN CLOSETS AND OR SMALL LAUNDRY ROOMS UNLESS YOU CAN VENT 700 square feet of unconditioned air space to them . They are noisy , but a garage in a humid hot southern climate is a good choice and with a time clock set for 11:00 AM to 4: 00 PM when the air in the garage is hot AND solar grid tied system is operating is a great strategy .
