First time here, first post. I tried searching before posting but did not find any relevant hits.
I am seeking help/guidance. I am interested in installing an electric tankless heater, primarily powered by solar but also wired to my home's electrical system as a backup. This is to replace my oil burning furnace. Key Points: I am using well water, so I suspect perhaps around 65 degrees inlet. The home has 2 full baths, 1 kitchen. Heat is currently baseboard water radiators. The solar hookup is only needed to power the electric tankless heater, not the entire home. I'm not having any luck while researching products finding what I am looking for. I seek advice on brands to consider, 'gotchas' during installs, brand quality and reliability, etc. Please help. Any advice appreciated. Thanks in advance!
