niether did I Dick and i used to work for them, 1990 to 1993, I learned a lot from them, they were pioneers of modern boilers, While all other manufacturers were using cast iron, they used copper heat exchanges, low water content,fanned flues,modulating gas valves, and combined feed and vents,

I've come across quite a few of them.
The levers used to leak after a few years, but hey what a simplistic idea it was and it all worked well, must have saved the customer ££££s in repair bills for MVs and other controls on todays systems.

Anyone remember those heat exchangers that you swopped the immersion heater for?
Thus saving the cost fitting a new indirect cylinder on a new CH installation?.
Cheap and nasty they were.

When my mum & dad had gas central heating put in their council house in the 80’s is was servowarm. They were the number 1 back then.

Microversion? Only heard about them because Tom learned me about them. Never seen one myself. Thanks to Tom, learnt a fair bit over the years.
Tom's even got a glowing reference from Plumber Pants on that vid.

that was one of the latest, the older ones had a steel surround, not as elegant as the wooden surround,

another innovation by Servowarm was, taking the flow from the boiler to the lowest tapping on the cylinder, this goes against all learning on central heating, but it worked good because when you think about it, they did a positive system the pump is pushing up the flow, So putting the flow into the cylinder return, pushed the air out, it made for quiet systems and quick recovery of heat to the domestic hot water,

they tried to take on the gas board, they were charging too much and they carried too many chiefs and not enough injuns, So the engineers were forced to charge and make more revenue, the customers fell off the data base fast and they went under, I believe they resurrected as homeserve, the original Servowarm was formed in Holland and thats were all their ideas came from and they made the boilers,valves pump valves and seals, no one else could buy them, they changed to Servotomic in the 80's and became an English company, So all the brains were lost, Soon they were selling rebadged boilers, they were buying glowworm,worcester,alpha boilers and putting servowarm badges on them, It did't take a genius to figure, " why buy a servowam part for £15 when a glowworm part is £5, that was the nail in their coffin,  |
