The radiators are controlled by thermostats, which help maintain steady room temperatures. I’m conscious that old timber-framed buildings are similar to fine antique furniture in the sense that sharp variations in relative humidity caused by large temperature fluctuations can distort or crack the wood. In my case, this could also harm some of the fragile internal plasterwork that’s awaiting repair.
The data loggers I’m using show that the heating has created a more stable internal environment. The only snag has been that one of the heaters developed a small oil leak. Fortunately, I discovered this before any damage was done to the building fabric and the supplier replaced the faulty unit immediately. The previous day I’d ordered a couple of extra radiators. By chance, they’re oil-free.
