I would like to get a tankless heater for my work lab and I am looking for those who have any suggestions for under the sink heater and if one needs a filter? Thanks in advance
I would prefer to get a propane type units petras, you have a preference for one of those to. Thanks for the inputThere are plenty of electric units available that work great and are super easy to install. That would be the route I would go if just using for a single point. The amount of power you have available would dictate how big of a unit you could possibly use, but for a single faucet anything from 5kw- 13kw (on 240v) would be sufficient for the use you describe.
Here is some literature from Richmond on their electric units. https://cdn.menardc.com/main/items/...ech_Spec/EssentialTanklessElectricT-660.2.pdf
If it were me looking to do what you want to do, I'd be looking at the RMTEX-8 or the RMTEX-11.
