Controlling Your heating

Choosing the proper heating controls for your boiler can often be confusing, but finding the right controls for your boiler, it allows you to take complete control of your heating system and never waste energy again.

As part of the Boiler Plus initiative, ‘smart’ Vaillant controls automate and optimise certain functions of your boiler, resulting in lower energy bills. At Warm and Cool, we recommend the Vaillant ‘Senso’ controls to ensure you always get the most out of your boiler at any time of the day without compromising on energy usage.

Vaillant System Protection & Boiler Filter

Protecting Your heating

Don’t let clogged pipes and rising energy costs become a headache for you. Proper maintenance is the key to ensuring your heating system operates efficiently. Neglecting it can lead to reduced performance and higher energy bills due to restricted water flow caused by debris buildup.
But fret not! At Warm and Cool London, we ensure your Vaillant boiler protects against the dreaded sludge buildup by installing a magnetic filter.

There’s no need to compromise on the efficiency and longevity of your heating system. Let Warm and Cool London help you say goodbye to rising energy costs and hello to a hassle-free heating experience by ensuring the smooth operation of your boiler, and increasing its lifespan, with the Vaillant magnetic filter.
