I had a new boiler installed a few years ago and i use to have a hot water heater attached to it,now with the new set up they did i dont have 1. a tankless or 2.a indirect water heater or 3. a traditional water heater like i did before. Now the water is heated from directly inside the boiler and it runs 24/7 and 365 a year (which i think is wasteful) and stays on in the chance i need hot water for my tub or kitchen faucet. What is this system called that i have? I have looked online and cant find what its called thank you.

    It’s a tankless coil and it is very wasteful.

    You could save at least 30% by getting rid of it and installing an indirect water heater.

    Adding an outdoor reset control would yield more savings and better comfort too.

    Youl’ll need a competent HYDRONIC contractor who knows all the particulars involved.

    I've had 2 different standard efficiency oil boilers that had tankless coils and switched them both to indirect water heaters. The performance is far superior to the tankless coil but I would not make the change to save money. My experience has been that the savings are minimal at best and you will never recoup your investment. In my current house I originally had an oversized pin style boiler with a tankless coil. Switched to an indirect and the savings were negligible. Earlier this year a new 3 pass, properly sized, boiler was installed with the existing indirect water heater. Seems like it's using less oil but I'll run the numbers at the end of the year to see how much of difference the boiler change makes factoring in degree days.

    If you really want to save money, stop using your boiler to heat a few gallons of hot water and instead use a heat pump water heater. I know you mentioned budget but your state may offer an incentive. It runs so cheap you won't believe it.

    Im from NY state so im not sure paul but that sounds good. Is this expensive for a heat pump water heater? https://www.energy.gov/energysaver/heat-pump-water-heaters I read from this i would also need a conventional water storage tank that holds 30 to 40 gallons to use along with that heat pump, this could get really expensive.

    Heat pump water heaters are self contained, they are essentially an electric water heater with a heat pump on top. They have their own storage tank. The one caveat here is that you have to have an electric service big enough for an electric water heater.
