Have used them twice now, once to disconnect/relocate radiators and another time to relocate the boiler. In both cases the team managing things have been very professional, quick but thorough, and clear re what was to be done. Particular thanks to James, Ronan, and Nick. Prices are fair for good quality work and service, will definitely reach out again for any other jobs.

We have been using Aren Properly Services since 2022, and always receive amazing care when doing our boiler services, or any remedial works. They always go above and beyond and never try to rip you off like a lot of contractors out there. Highly recommend

I had an issue with my HIU. I was able to quickly arrange a booking with Aren. Their onsite engineer was polite, friendly and punctual. He fixed the problem quickly and gave me some basic advice on what to look out for to help troubleshoot future problems. I would highly recommend Aren Heating and Plumbing.

Quick, clean and efficient. Very pleased and will be using Aren again. Ronan (the plumber) worked hard and fast to finish job inside 1 hour which kept the cost down for me, when he could have easily relaxed and stretched it out. Thanks!

How does a central heating Thermostat work?

A central heating thermostat is a device that helps regulate the temperature in your home by controlling the operation of your central heating system. It works by monitoring the current temperature in the living space and comparing it to the desired temperature set by the user. Based on this comparison, the thermostat sends signals to the heating system to turn it on or off to maintain the desired temperature.

What is a Smart Thermostat?

Advanced thermostats, such as programmable or smart thermostats like Hive or Google Nest, offer additional features like scheduling, remote control through mobile apps, learning algorithms to adapt to your preferences, and the ability to integrate with other smart home devices for increased energy efficiency and convenience. But the fundamental principle of comparing the desired temperature with the current temperature to control the heating system remains the same in all central heating thermostats.

Whether you opt for a simple programmable thermostat or a cutting-edge smart model, a well-installed and functioning thermostat will play a pivotal role in maintaining a cozy and welcoming living space while saving on energy costs.

Sounds complicated? It is, but not for Aren Heating & Plumbing. We are here to make sure you live in warmth and comfort without complication.
