This past summer we had the opportunity to tear out our main bathroom and start from scratch. One of the things we considered was how to heat the water in the new second floor bathroom. Would the boiler be able to supply ample hot water for the new tub? How about the new shower? Our pressure was always low, and it took several "fill 'n wait's" to get the old tub temperature to where it was not painful to sit in.
A new bathroom needed a new system. I talked hot water systems with Dave at Pioneer Oil, and he offered a lot of great advice. The neat thing about talking with Dave was he is a wealth of knowledge, and my decision to go with an oil fired system would be good, but if I didn't he was fine with that, too. He just wanted to share what he knew, and he knows a lot. So after researching, listening, and doing the pro's and con's thing many times, I decided to have a Bosch On Demand Hot Water System installed.

now takes care of all our households hot water needs.
My fear was the electricity it would take to to heat the water, especially for the large jetted tub, would be a lot, and although no oil would be used to heat it, I may loose out to the electricity. The research I did said otherwise, but still...
After air conditioning season passed, and I could begin to see the "true electric usage" I was amazed that our kilowatt hours were returning to our pre-remodel time for a year ago. There had been no huge hike in electrical usage despite the tub, and shower being used multiple times daily.
The last time we had oil delivered was in June, until this week. That oil usage was for heat, and for heating the hot water for the rest of our house. The delivery was for 121 gallons; not bad for almost half a year of heating water for the rest of the house, and the steam boiler for heat. I opted to see how well the On Demand heater would do with only the bathroom before I chose to flip the valve, and have the rest of the house on the On Demand System. Yesterday, we put the whole house on the system, and shut down the hot water heater in the boiler.
With our decreased oil usage to date because we put the new bathroom on the new system, and now putting the rest of the house on the system, I expect to save some more money that would normally be spent on oil. Sorry, Dave.
It will be interesting to see how our kilowatt hours do next month. Except for the dishwasher, we seldom use hot water elsewhere, and we use cold in the laundry.
When it comes time to change out your electric hot water heater think about an on demand system. The initial cost is more, but you will save a lot of money every month. It makes no sense to heat water in anticipation of it being needed, not with todays technology. Electric hot water heaters that heat 'n store are archaic, and a thing from the past.
Today, we have new technology, and its waiting for the rest of the world to enjoy it. My wallet is already smiling.
