Hi guys. I have an older style central heating system with separate radiators and hot water tank that is heated by a traditional gas boiler (not a combi boiler system) I have successfully automated the heating side of the system by using a Sonoff TH16 WiFi switch with temperature sensor flashed wi…

You can buy the DS18B20 not in the waterproof pack. It is then very small. I put mine inside the insulation around the hot water tank held on with a lump of blue tack over the outside of the chip, which survives the environment surprisingly well. Keep the first few inches of the wire against the …

Thanks for that Colin. Do you have a link to that sensor at all.

There isn't much point me sending you to a local supplier since I don't even know which continent you are on. Your favourite electronics supplier will likely have it. Or Amazon or ebay. It is best to buy from a recognised supplier though, there are many dubious copies about.

I am using the tube versions of the DS18b20, stuck into a small copper pipe, flattened for about an inch or two, then the flat section in intimate contact with the device to be measured... Plenty of heat transfer paste in the tube and between the mating surfaces help... Then, to finish it off, a sm…

As to Temp probe use the water proof temp sensor and make a hole in isulation, next to cooper/steel tank, fill with heat transfer compound and then insert probe. [image] TotallyInformation: It is probable that you would easily recoup the cost of the new boiler and fitting within a few years. …

Some fair points - we have a reasonable sized Victorian house in the North of England on a hill so it gets hit by the weather both from the North and South. 4 of us including 2 teenagers and a wife who likes a bath before bed. Our bills are "reasonably" large! You also missed both a pro and a con o…

You can also use this k-type sensor. It has a metal shield and work with chip max6675. [s-l1600]

[image] TotallyInformation: You also missed both a pro and a con of having a hot-water tank. Pro is an airing cupboard. As for reduced pressure, I think this is very dependent on a number of factors. As for boiler reliability The Airing cupboard has a pro to, you have a warm linen /towel cu…

I want to add my 2 cents in here. I am adding my flow for a wireless pressure and temperature sensor. Here is the company I dealt with. Pressure Transducers, Pressure Switches, Melt Pressure Transducers Wireless Transducer Solutions, Pressure Transducers, Pressure Switches, Melt Pressure…

Saving up for a modern combi-boiler would be a really good investment if that is a possibility for you. It is probable that you would easily recoup the cost of the new boiler and fitting within a few years.
