I have been very busy getting the Boler
ready for the Oregon Gathering.
It is almost together, new marker lights
are all in, rewired most of the electrical
(both 12V and 110V) and completely redid the plumbing.
As part of the plumbing update I relocated both the pump and the water inlet locations. I also had a 1 gallon instant hot water heater sitting on my workshop shelf and thought it would be the perfect size for the Boler
Yes this unit will only work when I am connected to 110V.
Water tanks like these are not designed to be pressurized. The tap that is included with the kit takes the pressurized water, the valve in the tap when turned on then allows water to flow into the tank and then hot water flows out of the faucet. (does that make sense?).
To replicate this design and ensure the tank would not be pressurized when the pump is running or street water connected I used a "wide mount faucet". This type of faucet has the spout and valves separate, they are connected under the counter with flexible hoses rather than the one piece brass construction usually found in most faucets.
I cut the hose between the valve and the spout and by adding some short lengths of hose installed the hot water tank in series. When you turn on the tap water flows into the hot water tank which pushes the hot water out the tap.
The original "Y" pipe that comes with the faucet, each end is designed to connect to the hot & colt valves, the center connects to the spout.
The line going to the hot valve is cut and tubing is spliced onto each side to make them longer.
