Have you found the reset button? Have you pushed it?

I know what lights are on the boiler, but are you saying that all those lights are ON ?

If the 160 auto reset is lit, and the water is at 60, then there's a problem with that circuit at the very least. It may be a faulty temperature sensor. That one should AUTOMATICALLY reset when the boiler cools to 120...

This concerns me... yes, I hope it works until May... but typically, well, never mind.

It sounds as if that 160 limit switch is 'flaky'. Fortunately, it's probably not an expensive part, but obtaining one might be not so easy. It's just a sensor on top of the tank, and has two red/white wires coming down to the circuit board.

Do you own and know how to use a multi-meter?

Is the off-peak still on? Has that light always been on?

Do you have the boiler connected to the power company load monitoring equipment? OR is there a blue jumper on terminals on TB1 ?

THANKS!

Of peak light is always on and I reinstalled the blue jumper wire just to take that out of the equation

I do have a couple digital multi meters
just tell em what to do...
thanks!

The next time you have the problem, set the multimeter to measure continuity, pull the red and white wires and see if the 160 sensor is open or closed...

When that sensor reaches 160 it OPENS, and should close again at 120.

I wonder if the temp gauge is whack?

In normal operation, I don't think there should be a reason for that to trip.

What setting do you have on the switch next to the blue jumper?

I think if that jumper is removed the boiler will still operate, but it will only run at half capacity... I think. Not sure... but that's kinda what the manual seems to say.

the boiler is set on 5 (135 degrees)

Are these mini boilers dependable?
I talked to the power company who supplied it to me and they say they quit selling them

When I did plumb the unit I did set it up to incorporate a a second heat source. Now am thinking of adding one of those super insulated 80 gallon water heaters,
I wonder if that would be more efficient since my electric rates have doubled in the past 7 years

I dunno really... never seen one... but yours has run for 7 years without trouble, that's not too shabby.

Safe to assume that you mean a gas fired water heater? If you do use a water heater, please make sure it's got the " H " rating to be used as a home heating appliance.

By the way, 10 PSI may be OK if your boiler is above all the heating pipes, but generally speaking, it's a bit on the low side. Is this a one story with only radiant in the bottom floor?

I was thinking a Marathon water heater
Marathon Water Heaters: For Consumers

the mini boiler is in the basement and heats the two floors above it with radiant infloor heat, staple up method
10 psi when cold and then increases to about 15 when hot

also when cold one pressure gauge reads 10 psi and the other reads 20 these are gauges that measure temp and pressure

I am quite sure that the Marathon's are not H rated.

You are aware that it's a plastic tank, correct?

The other thing to consider is that it's still electric! I don't really understand how that's going to be a savings for you, and these heaters are quite pricey. I think the 40 gallon was between 800-900 when I priced them several years ago. I'm sure the 85 gallon will be well over a grand.

Also, these are only 4500 watts. Which is HALF what your current boiler is. That's only around 15000 BTU and probably not enough to heat your home.

It would seem that one, or both, of your pressure gauges is not accurate!
