Boiler replacement

I have an old Patco boiler that I called in to have serviced. I know the aqaustat needs replacement and the stove pipe replaced as well. I have a battle with it every fall, seems like itís always something different... anyways, he recommended replacing it, I kinda agree. I donít think itís very efficient. With that said, I also need a new electric hot water heater.

ive heard that the new boilers are so efficient that I would need a hot water heater anymore. Could this be correct? Itís a small house, 1400 square feet. But would it keep up with showers and dishwasher kinda use?

please and thank you

If you decide to replace the boiler, replace the water heater too - with a gas-fired heater. No reason to use electricity - gas would be cheaper. Looking at the boiler nameplate, it is way way over-sized for the size of your house, 1,400 sq ft.

Can't tell the BTU'S but the boiler looks bigger than what it is I think because it is a steel boiler and only the top half has water and the bottom half is all chamber. You can tell by where the return pipe with the pump goes into the boiler. For a steel boiler you sure got your use out of it and then some.

Wouldn't recommend doing any large repairs unless a new one is not in the budget.

Not really in the budget, but a few more years of hot dogs and Mac and cheese wonít hurt us.
I guess my main question is, do I have to have a water heater at all? Can the boiler generate enough hot water fast enough to allow for showers and general household use?

Because... where I work is a house converted to a business, theyíve never had a hot water heater, just a oil fired boiler for heat in the winter. They recently had it replaced and can now run it year round because of its efficiency and we have hot water at our sinks. Could I do this at home or would my shower get cold very fast because of no tank? If I make any sense.

gently used patco boiler for sale... tell your friends

Spott..... the ID tag is in the picture.

There is no visible coil in that boiler so unless it's buried inside..... it won't be heating DHW for you.
Running an oil burner year round to heat DHW is not the most cost effective application.

I see what looks to be an electric water heater in the first picture it is the thing that says "Ruud" near the top left of the picture. Does it work if so that is your supply of hot water.

The Rudd is operational and is my current source of hot water for showers, sinks and such.

it needs to be replaced as well as the boiler. Iím wondering if there is a boiler that can do both?
heat my home and generate the volume of hot water that I would need for everyday showers, sink use, laundry and so on... Space is at a premium in there and I donít really want to go with a tankless water heater.

A brand new oil fired cast iron boiler, will run about the same efficiency as your current boiler.
Oil has hit its technological peak, and hasn’t really advanced much since. Besides condensing oil burning equipment. Which was a failure.

Thanks Pete. Imissed the plate pic and that is a good size boiler for that house but that doesn't seem to be the issue as much as the hot water. Pete if you look at the top of the boiler in the front you will see 2 pipes and a 3rd for the relief valve. I could be wrong but my guess is that is a tankless coil gone bad and replaced with the hot water heater. On those old steel boilers they sometimes mounted the tankless coil on top of the boiler and also he has a tripple action aquastat on there with high & low limit which I doubt they would have used if no coil was present.

As to the question of replacement wanting to eliminate the hot water tank you only have a couple options. Either get a boiler with a tankless coil again or replace the tank with an indirect water heater which would take up the same room as the tank but is more efficient or leave the boiler for heat and replace the hot water tank.

As a side note you could also just replace the tankless coil which initially would give you plenty of hot wat if installed and piped properly for a while but honestly that would be most likely my last choice. If your boiler is running fine then I might just look into replacing the tank from the info given.

One additional thing about domestic hot water. It all depends on how much hot water you use, amount of people and showers, washing clothes, etc. which only you know.
These are just my thoughts on the subject.
