By Ralf — Gas Safe Registered Engineer | 20 February 2026 | Radiator Installation
A homeowner in St Albans wanted to upgrade to striking anthracite vertical radiators without disrupting the existing Vaillant boiler system already in place. Ralf carried out the full installation, integrating the new radiators into the existing heating circuit rather than treating it as a standalone job.
Style and performance together
It's tempting to think a design upgrade like vertical radiators is purely cosmetic, but getting the technical side right matters just as much as the finish. Ralf upgraded the system with high-efficiency chrome TRVs and ensured the pipework was correctly balanced for optimal heat distribution across the whole property, not just the new radiators. Connecting designer radiators to an existing Vaillant system requires precision to maintain system pressure and energy efficiency — get the balancing wrong, and the new radiators can end up starving other rooms of heat.

Common Questions
Not without proper balancing. Connecting a new radiator style to an existing Vaillant boiler system requires precision to maintain correct system pressure and energy efficiency across the whole property, not just the new radiator.
High-efficiency chrome TRVs give more accurate room-by-room temperature control than older valves, and pair with correctly balanced pipework to distribute heat evenly rather than concentrating it near the boiler.
