Tankless WH for MB supplement???
I have an existing oversized tub in the MB. Existing electric WH is a lowboy to fit beneath house in crawl space (about 5 ft head room at WH). Not sure capacity but thinking around 35 or 40 gallons. Never issues with demand for hot water EXCEPT when trying to fill oversized tub. WH not able to provide enough hot water and tub is useless. WH is on the same end of the house as MB, so it's not an issue of just heat lost on a long run. Have been looking into options to address issue. Considering 1) electric tankless supplement, 2) electric mini-tank near tub, or 3) others??? Thinking that the additional capacity provided by the mini-tank won't be enough help, so was leaning towards tankless supplement specifically for tub. Reading lots of the posts about issues with tankless heaters, I'm questioning whether to go in that direction. I have plenty of room in panel for electrical requirements of tankless, but would have long wiring run for connection. Thoughts and options would be great! Thanks.
