What's a non stagnation area? #IgnoranceIsBliss

Or use intermediate vessel, but it is more likely no maintenance on the vessel caused problems.
Your overheating DaveI need a beer!
thanks.Thermal stores are still available & still have there place but as said before the amount of hot water (heat energy) you would need to store to provide for domestic heating & HW often means they are impractical.
Thanks, its also easy to get the heat out of water which, at times when people might not want to use much energy, has its own value.Looks similar to a wet (heating only) system I installed years ago at an outdoor centre. Place was off-grid and previously relied on a generator which had been replaced by a wind turbine and solar PV feeding battery storage & inverters with the genny as backup. Existing turbine controls dumped excess energy into a large resistor heating up the locality once the batteries were charged. We fitted a 1000L buffer tank with 4kW immersion heaters (8x500W) switched by the existing controls so instead of wasting energy it was used to preheat the tank. Heating was weather compensated with 3-way valve. According to the site manager the boiler hardly ran at times in spring and autumn.
Water might not be the best material for thermal storage but it's the easiest to install without getting expensive.
That's new to me. I thought that a high specific heat capacity was a good thing. I thought it meant that more heat could be contained.Remember water is actually a rubbish medium for heat transfer as it's shc is so high. We'd be better off using a different medium but it'd be more expensive and less 'simple' to service.
It's that double edged sword Greg. Reasonable retention but hard as hell to heat.That's new to me. I thought that a high specific heat capacity was a good thing. I thought it meant that more heat could be contained.
To store enough water for heating isn't on. You would need a massive amount of storage, just think how much water is contained in a central heating system & multiply it by the number of changes you need to keep the house warm.
