John Devonald has some tips on a topic rarely considered.
This short article is really one I should have written before winter set in, but I am still getting queries from people about issues they are having with their cooling systems. Here are a few points and tips to, hopefully, help anyone who is unsure as to what it entails.
On most canal boats, the cooling system is a closed loop with a water pump that moves coolant through the engine to cool it and then into the skin-tank to reduce the temperature of the coolant before recirculating it back to the engine. Tap-offs are used to supply the coolant to heat a calorifier in some cases. It is basically the same as a car but with the skin-tank taking the place of the radiator.
