Water Heater Insulation


You guys got any opinions on the best type of insulation for the boiler / water heater? Got some clients asking, and the brands I can find seem a bit rubbish... You guys know of a really good product I could order online?

Re: Water Heater Insulation


I personally think insulating a water heater is a waste of money,
The insulation from factory is more than enough, most of the money wasted is from the exhaust going up the flue ( on gas and oil type ) electric heaters are inefficient no matter what you do with them.
If you customers are concerned I would upgrade them to a power vented model that are aprox 90% efficient.
I'm not sure if rapping your water heater in a blanket is such a great idea.
Most insulation kits that I know of cost between $50 and $100 and don't let the homeowner or tech do a visual inspection of the appliance .

Just my opinion

Re: Water Heater Insulation


The cost savings are so Minimal its not worth it. You will spend more on a kit than the savings from using it.

Re: Water Heater Insulation


I've also personally never seen the need for one, but with energy rising in RSA, not everyone can afford heat pumps / solar geysers, and looking at other methods. I've heard of some people having their houses caught on fire when using blankets too. I just want to be a bit more informed on it from the mouth of guys who have tried it and if any one can say it works and saves money. But if not, then I will try look into other means. Recommendations?

PS @BC Construction.

How do the links at the bottom of your posts work for you? I've been told to do it for my Google, but I don't know what the actual procedure behind it all is? Could you also fill me in more on that please?

Re: Water Heater Insulation


Got to agree with the above - it is not worth it & those that can actually benefit from it should be replaced

Look into Marathon water heaters - highest insulated ones around

Best tip if they want insulation (electric only) is to place a 2" piece of foam under the unit - blue or pink, not the crappy white junk, your catch pan & then the heater

As for links - it can help & the help files will tell you how exactly - basically you are just editing your signature though I am not sure you have enough posts yet to do it

Re: Water Heater Insulation


Place your hand on a water heater...notice how it doesn't feel hot?

Re: Water Heater Insulation


It's stupid to push a customer towards a power vent vs a standard water heater as a means of saving money based on efficiency. Idiotic is probably a better word.

A standard gas water heater is dirt cheap to run. Period.

80% of my service calls on water heaters are on power vents. The reason to pick a power vent over a standard naturally vented water heater is to accommodate a location or if the old existing chimney isn't safe.

To recommend it as a means of saving money based on efficiency is ridiculous. Not to mention the price difference between them etc.

Wrapping heaters.

At one time in history that actually did help but not any more. Modern day heaters have 2 part liquid closed cell insulation injected between the jacket and the tank. It's kind of like spray foaming a house.......it's highly efficient. Wrapping does nothing.

Re: Water Heater Insulation


About a hundred service calls a month for me.

Rheem has the least calls.

A.O. Smith has the most.

Bradford white is really good also.

Parts availability from Rheem is excellent in every respect.

Selecting a water heater brand to stock and install has a lot to do with what a distributor carries and stocks. Often times this is regional.

I for one would never put a new A.O. Smith in a customers house even if they gave me profit incentives.
So far this year I had one warranty claim. It was a pressure switch on a power vent. Over a 100 units installed.

In 2012 I put over a 100 Rheem water heaters in. Had one service call on a defective controller.

In 2011 I had ZERO warranty claims.

In 2010 I had ZERO warranty claims.

Last week I had 3 A.O. Smith calls both were less than 4 years old.

Bradford Whites are dam good also. Hardly ever have service calls on them.

I'm a big fan of Rheem except the tank less, those are not good at all.

Re: Water Heater Insulation


I also find Rheem is the best....its what I use

and I also find AO Smith is the worst...when I can a call with a 6-8 year old heater leaking or not working its almost always a AO Smith

Isn't a power vented less efficient because of the electric motor?

Power vents are a "last resort" installation.

In 2014 it will be even worse. As of sits now they are very sensitive to pressure fluctuations and now the government is stepping in and forcing another 2% efficiency which translates to another $100 and more sensitivity issues on length of run and fittings.

I can buy 2 regular heaters for the price of a PV. Now consider main thence etc.

More efficient my azz. Avoid them like a disease.

I was almost going to install a power vent because the chimney Is shot. But like you said two water heaters for the price of one. Although the PV I seen around here are over $1200 and go up from there. I ended up running a b-vent though the only place I could make it fit.

The old owners left the new water at the house. I haven't got it hooked up yet because I got a problem finding the right size threaded nut to hook the water lines up to. This weekend I will get a pic and see what I am doing wrong.

I put one in because my chimney is shot. They are the norm here, most are GSW, Giant or rheem.
