Church heating

We are trying to provide an adequate temperature in our church, bearing in mind the exorbitant price of fuel and also the need to keep ventilation flowing to drive out covid. The system is good yet highly complicated and we are struggling to find best practice with the controls. Last weekend some found the church unacceptably cold: surprisingly there were complaints of overheating in the stewards area. One thing however is absolutely necessary. I have found that some one – or more – has often switched off the operation of radiators. That is not acceptable. If you find your chosen seat too hot then please move elsewhere.
