What does a TRV do?
A Thermostatic Radiator Valve (TRV) regulates the flow of
water into a radiator according to its setting to control the room temperature.
How does it work?
As the room temperature changes the element contained in the
valve head expands, adjusting a pin in the valve to open or close it. This
maintains the room at a set temperature.
TRVs use wax or liquid sensors which expand and contract to
adjust the pin in the valve. The type of material used can affect the
efficiency and accuracy of the TRV.
Historically, the performance of a TRV was judged solely on
its response time. Unsurprisingly, liquid was judged to be the more responsive
of the two. However, modern day comparisons have taken other variables into
consideration to provide a much more accurate judgement. Variables that must be
considered are; hysteresis, response time, high temperature, differential
pressure and accuracy. Once all factors
have been considered only then can a true assessment of the overall performance
of a TRV be accurately determined.
Hysteresis measures the ability of the valve to maintain a
consistent room temperature within comfort limits.
Response time measures the ability of the TRV to respond to
temperature changes within the room.
Differential pressure or force is what drives the pin and
opens or closes the valve.
Benefits of wax – the original material used in TRVs
Smaller: more compact
sensor element allows much better designs for air flow
Safer: wax has anti- flammable properties
Quicker: faster response time once different temperature has
been set
Reliable: uses a thermally conductive copper flake in
suspension
Long-lasting: wax is less likely to leak
Consistent: greater force prevents valve sticking and
ensures valve performs when commanded by the element
Benefits of liquid – a more recent alternative
Faster to detect changes in temperature
Did you know: 68% of TRVs sold in the UK use WAX

Pegler goes the extra mile to create a sustainable future and business
The benefits of the whole VSH Tectite range and its heat free jointing, cement its market leading status as a metal push-fit system in the UK
Health and safety is something that has been at the root of operations since the very beginning at Pegler and so we are holding a health and safety week to maintain traction
Contractors are frequently asked to deliver work faster and more cost-effectively than ever before. Removing the risk of squeezed margins while at the same time delivering on time and on budget can be achieved by working closely with building products manufacturers such as Pegler who can support contractors to deliver projects faster, safely and profitably.
It’s been a turbulent few years for British businesses. Some huge names have disappeared from the high street and the next 12 months won’t be any easier for companies, whatever their industry.
At Pegler, we pride ourselves on our reputation for quality and innovation in an industry where product reliability and versatility is demanded. Our jointing solutions span the full range from the tried and trusted traditional to the newer modern methods such as push and press.
Pegler is delighted to announce that we have joined the leading Yorkshire manufacturing and engineering membership group Made in Yorkshire.
Social media is often under the spotlight for the negative things that can happen on Twitter, Facebook and Instagram. But sometimes it can be a force for good too.
Designers and installers of pipe-work systems, whether they are for domestic, commercial or industrial projects, are facing increasing pressure to deliver more cost-effective solutions which optimise performance and conform to exacting quality standards.
As part of our commitment to our local community, we’ve been supporting a number of initiatives designed to help young people make their way in the business world.

As part of Pegler Yorkshire’s community
engagement activities, Farah Yasin from the Marketing Department went back to
school to help out with this year’s TEKK Challenge. Here she describes how the
10-week programme has helped pupils get to grips with science, technology,
engineering and maths skills…
As a specifier or contractor of commercial plumbing
and HVAC systems you are probably already familiar with the benefits of using
stainless steel pipework systems.
As a manufacturer, we know only too well
the truth of the saying “you’re only as good as your last performance”. Our
customers (and their customers) judge us on their most recent experience of our
heating and plumbing solutions, which is one of the reasons we are continually
evolving our ranges, as well as our processes, to make sure we provide the very
best products and services.
Clive Gill, Technical Information Administrator, has been responsible for managing the processes we use to share product data with our customers for over 10 years. He shared his experience of getting to grips with Building Information Modelling (BIM) at last year’s Bathroom Manufacturers Association (BMA) BIM Workshop which took place just before its annual Bathroom and Kitchen Business Conference.
Well over half the work being carried out by heating engineers and contractors is on “live” sites, where traditional jointing methods can add extra workload in terms of paperwork and meeting health and safety requirements. Switching to modern press-fit jointing methods minimises on-site risks and means contractors can get on with the job in hand safely and quickly.
