Buderous water heater crapped out, looking at a 40 gal crown SS model, $992 in stock locally. Any opinions?

I have no idea, but if you're making a man cave down there, doesn't that oil hot water heater make some noise when it's firing?

No, I never hear it. Plus, the furnace/wh is on the other side of the chimney, not in the office/lounge area. The chimney is 10' wide.
Also, our oil burner is 85% efficient, dhw, uses very little oil. And we only have 3 people here, albeit 2 are females.
Will the electric HP roi be worth the expense?

No, no vent.
Electric resistance is 100% efficient - heat pumps 1.5x +/- better than that and can add some a/c & dehumdification effect while doing it.
How much oil do you burn say in a month for DHW?
A very small amount. It seems the oil level doesn't change much from May to October, while we aren't using the heat.
do you have a boiler? tap off the boiler with a superstore made in mass. htp products. you'll use about the same oil and it will recover from a shower in about 10 to 15 minutes. all the bedarus boilers i have wired are going bad one by one none are making the 10 year old mark. i have had my superstore 14 years on harsh water and no issues
We currently have a buderus oil boiker g15. How much does the 40 gl tank go for? And is there much benefit to double wall?
So will a heat pump setup for a 40 gl tank be much more expensive than just slapping in a new tank?
Take a look at the GE Geospring. 50 gal tank, 5 different mode settings, heat pump, hybrid, electric only, high demand, vacation setback.
Lots of info floating around Hearth about them. The early ones had some compressor issues, now that they are made / assembled in KY they are much more reliable.

the htp superstore runs about the same as a pvc chimney type water heater. the heatpump style is a touch more. i'm not sure about the double wall because i know nothing of it. if you are looking to have a fast recovery water tank go with the superstore and make sure it is piped in with 1 inch pipe. my superstore recovers in 10 minutes between showers or a little over 15 minutes from dead cold. if you have a low flow shower you can shower all day long. i have a low flow showerhead and don't turn the water up all the way on my shower valve and it won't get cold unless i'm running the clothes and dishwasher at the same time i'm in for a long shower. it's a 45 gallon tank

I have read on here about people getting a Heat Pump heater (like a Geospring) for quite a bit less that I can get an ordinary electric resistance heater. There are some very nice rebates & incentives in some places. Or there were at least.

You can get a 40gallon name brand electric hot water heater for $300. Install is a snap. Plumping is a snap. Running the electric is a snap.
I did the conversion for my aging boiler and I don't regret it for a min.

I have a Superstore Ultra SS indirect running off gas. Over 10 years old now and never had a single problem with it, FWIW.
But I agree if I was on oil I'd seriously think about getting an electric, heat pump, etc.

Amtrol Boilermates have good reps.
I have the 80 gallon buderus tank with two coils.
We never run out of hot water but we never did with the old tankless burner either.
I have the Logano G115 with a riello burner and it runs 89.7% eff without the logomatic control.
Outside air kit and thru the wall exhaust.
From Bill Battles.
Doesn't make sense to me to heat the house with oil and DHW with electric. If you had an old furnace with lots of waste heat to give up to a heat pump electric heater or a wood stove in the basement maybe. Not when you are already capital invested in a boiler sipping oil. Invested in PV panels the numbers might favor a heat pump.
Heat pump heaters can't compete with these low gas and HHO prices .
Not with Ma. electric rates.

never seen a amtrol go more than 12 years. they rot and leak at the bottom fittings and the top where the t+p valve go's

Pros & cons to both.
Also might not make a lot of sense to use a boiler for DHW if it's rarely used for heating the house. Not sure how much the OPs boiler is used for that, there are 4 wood stoves in his sig. Plus it also adds to the cooling load in the summer time. Heat pump heaters can absolutely compete with gas & HHO prices, they are twice as efficient and lots of waste or extra heat is not required.
Run the numbers with $1.80 HHO and $0.27/kwh electric rates
don't forget to calculate the replacement BTU costs from the heat losses to the room(s) affected by the heat pump extraction. Otherwise you are comparing apples to oranges.

I have the Logano G115 with a riello burner also. Old tank was 32 buderus. I use oil burned only for overnight setback heatng and DHW. The DHW used very little oil. The heat pump option would require new electrical work, and other piping work. I don't believe the benefit, in my case, is there.
