Boiler Basics

Boiler

This is our boiler. It provides our hot water as well as pumping warmth through the radiators to heat this drafty flat. The entire contraption is only 32 inches high and 25 inches wide, which is downright minature compared to the 50 gallon behemoth that we had in Oakland. The size difference is due to the fact our unit here is “tankless” versus the tanked variety we enjoyed in the US. (The New York Times has an insightful article on the raging debate between the tanks and the tankless.)

Regardless of the technical differences, we actually have no idea how the boiler really works. We have managed to figure out how to set the timers for both the hot water and the heat. We know its 5:00 am when the radiators begin gurgling as the hot water moves around. We also know that the whole thing just quits now and then. We learned this the first time through a very cold shower. The remedy is to reach behind the boiler for the hidden valve to replenish the water that occasionally boils off, leaving internal levels too low for the boiler to function properly.

The best thing about this system is that the “radiators” for all the bathrooms are simply heated towel racks. Nothing beats a toasty warm towel as you step out of a lukewarm shower.

The worst thing is that the boiler is temperamental, unpredictable, and the landlord opted out of installing a central thermostat when he built this palace. The heat is either on or off, with a valve at each radiator to control individual room heat. When the weather changes we make the rounds to adjust the valves again.

We dream of our digital and centrally-controlled heating system in the U.S.  I guess we should be grateful we are not shoveling coal for heat!

You're supposed to be grateful for your heated towels. Ever thought of using them while you watch TV in the evenings???

Sounds like a badly installed system to me. One with a leak somewhere too. You shouldn't need to top up the system - needing to is a sign that airlocks are developing. The only way they develop is if water is leaking out somewhere - that's probably why you hear gurgling. Likewise, the thermostat. A central one should be fine so long as the radiators are correctly sized and the stat is located in the right place. Pity me. I'm on a district heating scheme and there is no thermostat. While the limitless 24 Hr hot water is welcome, but the only control I have, winter or summer, is to turn radiators on or off Currently, only 2 are on in the whole house! If I ever turned them all on, I'd be cooked alive in my own home!
