Its design, craftsmanship, and important accessories all contribute to the Sunbank’s high performance and long life span.The Sunbank water tank is insulated with 55mm of HDP insulation. Its design, craftsmanship, and important accessories all contribute to the … Take a look see.
This makes sense because the cost of the insulation you buy should not depend on the thickness of the original insulation. I’m glad that I found your website. I partly agree. Great post.Hi Pondered. Generally when a leak develops they are slow
I don’t see any way the air can come to bottom burners?From Australia so figures are all different!
This allows you to keep track of the temperature in your tank.The Sunbank Controller measures the temperature inside the Sunbank and can be used in conjunction with the auxiliary heater. This is about the same price as some insulating blankets designed specifically for hot water tanks, but it is enough for about 12″ of insulation around my tank which is more than 5 times what you would get with an insulating blanket. (PS I was reading about that model passive house in Illinois.

)If you want to reduce your heating bill… More than insulation alone…Run your INLET water up to your attic, at the peak.

You can think of “cost” in terms of dollars or in terms of environmental footprint depending what your concerns are. It can be set to whatever temperature range so that it will only activate the heater when the tank temperature dips below a defined temperature. The images below sho before during and after insulating my hot water tank.Although these images show what appears to be a gas hot water tank, I must emphasize that it is not. @ Noirceuil, Thanks for being on the ball and checking my numbers. This is because of the “Time value of money”.

2) I noted that both the cold and hot water lines going into the water heater (before insulation mod) did not have dielectric connections from the copper pipes connecting to the water heater.

Assuming you’re primarily interested in saving money, it’s fairly easy to estimate what you can save by adding more insulation to a hot water tank. Thanks for the comment. It actually feels cool to the touch, so seems unlikely it is losing much heat thru the walls. I can assure you that the radius of my hot water tank is significantly greater than that ;-). Due to be replaced within a few years.) Blazing Hot? Adding 5cm costs only $1 but will in theory reduce operating costs by about 5% (the percentage increase in insulation thickness) saving about $5 per year on the current $100/yr operating cost. The suggested insulation for an energy efficient home is for R40 walls and R60 ceilings. If your attic is 200 m2, which is reasonable, then your walls must be approximately 14m on a side or a total of 56 linear m. If you have 1200m2 of wall area, your house is 21m high or 7 stories.But remember insulating your hot water tank alot will make the wires inside the tank get HOT and could cause a fire!!! There is no point at which adding more insulation will cause increased heat transfer. Based on my estimates above that might offer around a 10 year payback.

Having now monitored my complete electrical consumption for a mere week and a half, it is most likely that we have considerably more circuits in our 1913 home. So if you can't lay your eye balls on the water heater (cuz there all in boxes, except what's displayed) then go with the best (unless there is a significant cost difference to compel you to go with the "better" branded water heater).Oh if your doing it yourself, then always get fresh lead free flux. F is the thickness of insulation and has units of length (cm in this case). A house has the added complexity of different insulation thicknesses for attic, walls, basements, crawlspaces, doors and windows, and three modes of heat loss: air leaks, conduction to the air, and conduction into the ground.

If I simply wasn’t clear enough, then I’m interested in explaining myself better.PS. At least it was continuous when installed, seems like I have been punching holes thru it for 25 years. Based on my estimates above that might offer about a 15-20 year payback.

My assumption is that a well insulated wall and ceiling will pay for itself in low heating / cooling costs and inert insulation requires no maintenance during the life of the house.
