| 568399 | 2007-07-12 21:10:00 | The point is that the new cylinder loses heat faster than the old one in spite of all the advertising blurb about "energy efficient" etc. And yes it is slightly thinner but virtually the same height, one would hope that the "breakthroughs" in new insulation techniques would have obviated the tendency away from the ideal sphere, being the object with minimum surface area vs volume. My old one was tall and skinny but it was a Peter Cocks 180L. This is shorter and fat but is Coopers. Its colder on the outside than the old one. Which husband complained about, he said his beer kit had dropped 4 degrees. :D The new cylinders can't be turned up to as hot a temperature and additionally are meant to be fitted with a valve to limit it as well. They are supposed to be a 55 degrees. Ours can have a maximum of 70 without the valve. The old one could go higher. |

| 568400 | 2007-07-12 21:43:00 | I've had 2 older cylinders replaced with the newer polyurethane foam insulated type. They definitely are better insulated. The only warmth in the cupboards comes from the copper pipe coming off the tank. The Coopers one has an external thermostat going to 80. The tempering valve is adjusted to be 55 at the basin, bath etc. zqwerty - is the outlet pipe insulated, how does it run after leaving the top of the tank? Heat rises so best practice is for the pipe not to go straight up. |

| 568401 | 2007-07-12 22:32:00 | We got rid of our hot water cylinder about 5 years ago because it was in a really dumb place in our butchered 1920's bungalow. We replaced it with a Bosch gas water heater which not only gives a continuous supply (i.e. we never run out of hot water when the parasites arrive to stay), but it provides near mains water pressure and flow. As you know, old houses that rely on a water tank in the ceiling to provide pressure tend to supply a dribble at the shower head. Now we have lovely luxurious showers, more space in the dining room where the cylinder cupboard used to be, and we never run out of water. Not sure if the same problems caused by your water supply would arise with a system like ours that doesn't store water, but it may be worth checking out. I gather from a neighbour that this sort of system is not economic if your home contains a teenage girl... :( |

The shower pressure is just fine and not a dribble at all. Likewise the outside hose. All depends how you have your plumbing hooked up. |

Indeed. I was only mentioning the pressure/flow situation as an added benefit (to us anyway) of changing from a storage system of hot water heating to a continuous flow "heat as you go" method. The main point I wanted to make was whether a water heating system that doesn't store water would help in your situation (where you have high acidity that leads to premature decay of your cylinder). Even if the acidity damaged the gas heater as well, perhaps it would be cheaper to repair that, than replace a whole cylinder every few years? |
