  • Instant hot water out of sink faucet
I purchased this under sink tank for the cabinet in my bathroom. It has very tight space so small heater is ideal. The heater comes with all the parts to complete the job, including adapters, Teflon tape, t-tube, pressure relief valve, etc. the temperature control is quite accurate from 86 to 167F. It can be mounted flexibly in three ways, with wall mount bracket, rack and floor. Make sure it is close to an electric socket on a breaker that can provide up to 20 A. I imagine this will be a perfect solution for cold winter. ... show more

  • Awesome upgrade to Motorhome! Electric &lpl Awesome upgrade to Motorhome! Electric &lpl
Model: BI-8G
I found this water heater to be just the trick when you're paying for an RV site or just want to use electric the 8 gallon capacity is plenty I replaced my atwell 6 gallon by incorporating a few t's and some shut-offs in the packs made a few holes into the cargo hold and I was able to put this 8 gallon in, we almost never use the propane since we pay for the electric at the RV sites and it's just easier to operate the electric it works great! ... show more

  • Great replacement for camper water heater!
Model: BI-4G
Awesome replacement for my camper water heater. Only issue was finding the right fittings to hook it directly to pex. Ended up having to use shark bite fitting from Lowe’s. Heats up really fast so putting it on a switch was an easy way to conserve power.
