I'm rehabbing a 3-story 1911 house outside Philly. I have a new boiler. I'm pretty sure I want to zone the system. It's just the wife and myself, so there are several spaces that don't need to be fully heated every day. I have a couple of questions as I research the topic. 1) Should I be concerned about short cycles? The boiler seems a good fit for this house. If I could achieve a 30 percent drop in run time am I raising a risk of short cycle problems? 2) Which is better, valves at the boiler or valves at the radiators? I've seen TRVs and some thermostat controlled valves and it seems like valves at the radiators is ultimately simpler. On the other hand it seems like you could set up valves at the boiler so you could do repair and maintenance without draining the entire system. Any thoughts, suggestions, or resources for further research? Also 3) what about cost recovery? How long is it likely to take to recoup my money? Thanks.
