Getting started replacing oil boiler with gas OR heat pumps?

wait, now that i think of it the hyperheat system i put in my brooklyn townhouse in 2015 to do all the heating and cooling is still running good as new and has never needed any repairs beyond seasonal maintenance. so that’s 8 years ago. i am officially calling BS on chris’ claims.

Hi all, we are hoping to replace our oil boiler used for steam heat in our Bedstuy brownstone this summer.

Based on speaking to old school contractors, everyone is recommending converting to gas.

But online research tells me that heat pumps *could* be a viable option.

I’ve gone down the google rabbit hole a few times on this, but there seems to be so much conflicting information out there (and of course, most of the info one way or another is published by people with incentives to push one technology or another)

Can you guys recommend any resources as we just get started on trying to do this upgrade?

Resources as in to try to compare which option is more efficient or contractors to compare the costs?
If you go Oil to Gas, you definitely need permits and likely additional work. If you go Electric, you may be able to do it without but it also depends on how you produce Domestic Hot Water

I am as confused as everyone else in this but i will share what i know.

I used heat pumps when i lived in modern (read “well insulated”) student style apartments while in college in wilmington, nc in the latter half of the 1980’s. I always felt cold with them and now know why, they have to be left on all the time as the produce heat slowly, over time. There was something else; the older technology did not really produce heat on its own once it was below 32 degrees Fahrenheit at which time an electric coil kicked in and that cost a lot of money.

Apparently today’s units are a little better. I have not read about american technology (trane, carrier) but someone on here pointed out that units being produced in europe are now being used in nordic countries. So i looked up the technical data on some produced in the UK. They themselves admit that once the temperature drops below 28 degrees Fahrenheit, they start to become less eficient all the way down to 11 degrees Fahrenheit at which point they produce no heat and an alternative heat source must be used. They warn people living in Canada (the uk company exports to them) that they can not rely on these as their sole heat source.

The suggestion i have heard from some on here is if you want a heat pump, keep you old system as back up.

They are installing a lot of gas heating systems in europe that do the same things ours do, not with steam, but hot water. These units are smaller and fit under a kitchen cabinet. My guess is there is not a lot of heavy cast iron in them and the radiators are smaller, thinner, and are set up so they can be isolated from one another (i spoke to someone in europe about this and forget if he said “zoned” heating or by each radiator). Since they are compact. There is probably less water to heat = more efficient. I see them in houses in this country made by Bosch, so they are available here. One of the heating guys on here can speak more to these units.

Read some of the older posts on here about this topic. It seems to be all over the place. I think a lot of people want to move in the right direction but are not sure what to do and some of us sitting on 30 year old boilers know we’ll have to do something sooner than later.

here we go again……i switched my house upstate from oil to heat pumps. they work great, the house was built in 1850 but has since been upgraded and is fairly well insulated. I have 6 “zones” which really just means each indoor unit has its own outdoor unit and each can be turned on and off as needed. my electric bill has gone up but it is half the cost of what i was paying for oil. not sure how that compares to gas.

randolph, are you up there all winter or here most of the winter? how do they work when it is down around 20 degrees F? if you are here in the winter and go back up there for say weekends, how long does it take to heat a house (as compared to our dino steam heat)?

technology wise, how does the mitsubishi compare to the american stuff? I mean do their specs claim to function as a heat pump at lower temperatures than american stuff?

i seem to remember you were going through this and am sorry if i missed you coming on here and saying how this worked out.

it works like any other forced air system, the smaller rooms heat up faster than the bigger rooms but we have never been unable to keep it at a comfortable temperature even on the coldest days.

i know nothing about other manufacturers, the people we used to install only work with mitsubishi.

never mind randolph:

from mitsubishi:

“….If you live in an area with extreme cold-weather conditions – not to worry! Mitsubishi Electric offers heat pump systems with Hyper-Heating INVERTER® (H2i®) technology which can provide up to 100 percent of heating capacity at 5° F and continue operation down to -13° F even without auxiliary heat. Select units equipped with Mitsubishi Electric’s H2i plus™ technology can deliver up to 100 percent heating capacity down to -5° F.”

We’ve had some basic dialogue with architects about a (down-the-line) full renovation, and the consensus seems to be that mitsubishi hyper-heat ductless system is the way to go these days. Assuming the performance and cost is even similar, the benefit of freeing up floor space from getting rid of radiators / pipes / boiler would be enough for me to do it…

How does it work ductless? How does heat get moved around? How many breaker slots (are they 220) does each one take ? How much are they and can a homeowner with reasonable mechanical/electrical skills do this kind of install?

Maybe mini split is the more precise terminology as opposed to ductless. It’s a standard heat pump mini split system with air handlers in each room, but I guess the “hyper heat” technology is what is allowing these to be reliably used by cold weather climates without the need for radiator back-up for even the coldest days

Randolph, how many actual pump units do yo have and how many air handlers? How many breaker slots did this take?

Does anyone know if heating and cooling capacity is the same on these, ie, if it takes 8000 btu to cool a room, is it the same to heat it?

there are 6 indoor wall mounted air handlers and each has its own outdoor unit. i do not know how many breaker slots it took, the outdoor units are on two sides of the house each side with 3 and there is one electric box on each side that they are wired into. i did not have to upgrade my electric service, I believed they used the circuits from the old forced air system that was in the attic.

I am in the midst of a townhouse renovation and we are installing a multi zone hyper heat mini split system for both heating and cooling. We are using Daikin instead of Mitsubishi (although Mitsubishi is considered the gold standard of mini splits). The property is a 3 family house, with 2 smaller apartments and 1 larger one. Each smaller one has its own 36k btu condenser (the outdoor unit) connected to 3/4 indoor units and the larger one has two 36k condensers connected to 6 indoor units. Each apartment can control all of its indoor units on your phone or with a hardwired thermostat. We are also installing a few supplemental electric hydronic (more energy efficient) baseboard heaters and electric radiant floor heat in the larger bathrooms. While the project isn’t done and I can’t speak to our design’s success yet, I definitely recommend going with the hyper heat mini splits over gas. If you hire a good engineer to do load calculations (aka how much heating/cooling capacity you’ll need) and design the specs/layout of the units, you will have no problem keeping you r home warm in the winter. The units we have can heat at 100% efficiency until -5 degrees F and goes down to 75% efficiency when it reaches -13 degrees F. Given that NYC hasn’t reached below -1 degrees F in the last 15 years, the units will have no problem. From my past experience, the biggest factor in a successful system is a high quality installation, so make sure you work with a reputable company. If one of the refrigerant lines gets bent too sharply, you could have a leak on your hands that you won’t know about until its too late and possibly have to rip up all your walls to find it.

Gas is going to become obsolete eventually, so might as well future proof your home for the future with an all electric system! Plus, there are tons of rebates on mini splits, especially if you are converting from oil.

Look into what “hyper heat technology” is. I know we all want to believe it’s environmentally friendly magic sent to earth by Jesus himself, but it’s a costly version of electrical resistance heating, which is basically the same “technology” as what makes your toast in the morning.

try to read what hyper heat tech is and they talk about “Invertor Technology” without explaining that –

I spoke to two people yesterday who mirror what mp is saying.

> environmentally friendly magic

as more and more electricity comes from renewable sources isn’t it fair to believe that heat pumps are more environmentally friendly than burning fossil fuels? It may not be perfect right now, but is it not trending in the right direction?
