Does this unit have freeze protection? I live in southern Virginia and the winter temperatures go below freezing Thanks Dan

Asked by: dan
I do not think that it has freeze protection but I read the Use and Care Manual that the system had a DIP switches to set at different altitude 3,280 Ft (default), it could be set DIP2 third switch to "On" for below 6,560 Ft (I guessed; it is colder in High altitude; It could apply to cold city with low altitude). Good luck and check the Rheem expert for the solution of your issue.

Is this unit (9.5 gpm) sufficient for both domestic hot water and space heating through a hydronic air handler? Does it have connections for both?

I need a unit for both domestic hot water and hydronic space heating via a hydronic air handler, with separate controls for each.
Asked by: Bob
You can use this heater for both domestic hot water and space heating with a Rheem approved air handler.

9.5 GPM Natural Gas High Efficiency Outdoor Tankless Gas Water Heater is rated 4.8 out of 5 by 4.
Rated 4 out of 5 by from Easily installedon exterior walls without having to run a flue or roof penetrations. Only needs a 1-2 ft clearance from eave Good heater if you don't want to deal with roof penetrations and flues etc. Vent directly to outside. Eave clearances not noted in instructions. Had to call manufacturer to get this info. Otherwise good product for use on exterior walls.

Rated 5 out of 5 by from time for a change to new technology Glad I had a .75 inch gas line available, because I didn't read the specifications before purchasing this unit but it worked out great. I have a lot of old steel piping in my old house and this unit works well after I increased the water temp to 140. I'm glad I located the unit on the other side of the house because it does make noise with the fan. Careful where you drain the condensing water, I may have hurt one of our plants, a little to acidic. Remember to check the filter. Works great, no more running out of hot water for the Jacuzzi tub.

Rated 5 out of 5 by from Excellent product.. I am no plumber. But I installed it in about two hours. I works great and is extremely quiet.

Rated 5 out of 5 by from Tankless Water Heater installed outdoor style, replaced a Noritz model, works better than the Noritz. Will take two people to mount, its heavy, used molly bolts to secure.
