I recommend that you do a "true" heat loss calculation. Takes only a couple of hours using a computer program, either available here or elsewhere.

Spot's suggestion is good - to clean the strainer on the inlet of the backflow preventer. A Watts 9D backflow preventer will require isolation valves on each side to open the strainer. (The main...

My old hot-water boiler has been set up for warm start for 70 years. I've considered converting it to cold start, but there has been a concern that the larger number of thermal cycles might lead to a...

Warm-start vs. cold-start boiler

My 70-year-old gas hot-water boiler has always been set up for warm start. I could change it, but there may be some reasons not to. The heat "lost" from the boiler into the basement boiler room does...

I take it that you are planning to buy this from some reseller, not an authorized dealer, installer, or contractor? I would be a little leery of that unless you are sure that warranty service will be...

Yes, you can have a separate water heater

Your question: "Also is there anyway to use the boiler just for heat and get a separate water heater."

Yes, it is very common to have a gas-fired water heater, separate from your heating boiler....

Converting standing pilot to Intermittent (spark) ignition

Our 70-year-old Kewanee gas-fired hot-water boiler is running great. But the standing pilot assembly is a pain. The boiler was originally compatible with hot-water, steam, gas, oil, or coal - ours...

I don't think all those tests could be competently performed for anywhere near $79. Maybe they want to get their foot in the door and sell some costly repairs? I would not respond to a postcard...

I'd go with the shorter rod

The longer rod piled up on the bottom of the tank probably should be OK, but why risk it. Good luck.

Another thought

If the Taco pump is marked "IFC," it means it has an integral flow check valve. If so, that loop doesn't need a separate flo-control valve - and you could just remove the flo-control valve altogether.

I agree

I think that B&G valve is the problem. Could its handle be on backwards? If not, replace the valve. In the meantime, de-energize the punp - running it at shutoff head will eventually burn it up. Good...

The only thing you should have done is not ignore the leak. No leak is acceptable. Get it fixed even if it's just a drip.

We would need much more info and photos. This situation may be beyond your experience level as a DIYer. I recommend that you call in a pro whose references you have checked.

I would try another heating outfit. Or do you have a handy friend or neighbor that can use a "real" voltmeter? The troubleshooting we are suggesting is not rocket science. Otherwise, beg, borrow, or...

That "smart" voltmeter - not sure how it works, but it isn't measuring the voltage across the two 24-V terminals on the gas valve - just one. Get a voltmeter with two leads that has a dial that...

What is the full model number of the Taco pump? The recent versions have a nylon impeller - which I wouldn't expect to shatter. And they are now white.

Lack of maintenance

That photo shows serious lack of maintenance. That air eliminator has been leaking for a long time. If you don't feel confident in your DIY experience, call in a qualified pro at least once a year to...

What you are describing is a combination pressure reducing valve (a.k.a. automatic feed valve) and a safety relief valve. Either B&G or Taco are fine. Nowadays, it's more common to install separate,...

Probably the plumber didn't verify the air pressure in the tank before installing it? Depressurize the system, and check the air in the expansion tank with a tire gauge - let us know. Alternatively,...

Humidifier for Hydronic Heating

With hydronic hot-water heat, we have no HVAC ductwork in which to mount a typical whole-house humidifier used with forced-air furnaces. My first solution was to have two portable humidifiers -...
