I’ve been on a mission to optimize my heating system and reduce energy bills, and I thought I’d share my journey and findings with the community. My setup includes a Vaillant Eco Tec Pro 28 boiler, which I’ve been tweaking to find the sweet spot between comfort and efficiency.
I live in a three-bedroom flat on the second floor, built around 2000, with 10 radiators. The boiler handles both heating and hot water, and I also have an electric shower. My goal was to see if I could lower the flow temperature without sacrificing comfort. After some research, I decided to drop the flow temperature to 46°C and set the radiators to 18°C overnight and 20°C during the day using my Tado smart thermostat. This setup has been running consistently, and I’ve noticed a significant reduction in energy consumption compared to previous winters.
One thing I’m curious about is the boiler’s range rating—whether it’s set to auto or if it should be adjusted manually. I’ve been unable to locate this information in the user manual or online, so any advice from the community would be greatly appreciated. Is there a recommended setting for a system like mine, or is it something that can be left on auto without issues?
Another observation I’d like to share is that while I’ve been experimenting with keeping the heating on all the time, I haven’t seen a huge difference in costs compared to cycling it on and off. It seems that maintaining a steady temperature with lower settings might be just as efficient, if not more so, than constantly adjusting it. I’d love to hear how others manage their heating systems—do you prefer a constant low setting or cycling the temperature throughout the day?
If anyone has tips or tricks for further optimizing heating efficiency or insights into boiler settings, I’d be thrilled to hear them. Let’s keep the conversation going and help each other save on energy costs while staying comfortable!
