What is a Thermal Store? Video Animations

A thermal store, also known as a heatbank, buffer or accumulator tank, is a way of storing and managing renewable heat until it is needed. The water inside a thermal store contains inhibitor and will flow around all of the connected heat inputs and outputs, we call it 'dirty water'. Domestic hot water can be supplied through the use of an instantaneous heat exchanger, which extracts heat from the dirty water and transfers it to your mains pressure hot water taps.

Thermal stores are an exciting and innovative alternative to a conventional heating system, which has many limitations when there are 2 or more heat inputs. At TMS we design systems that use high temperature inputs, such as a boiler or wood burner to heat the cylinder from the top down, because 50 litres of hot water is far more valuable than 200 litres of warm water. Low temperature inputs such as solar and heat pump are used to heat the cylinder from the bottom up.

TMS - About Us

As renewable energy pioneers, we have been designing and installing solar/wood/wind/PV storage and underfloor heating for over 25 years. With such broad experience, we find ourselves uniquely placed to offer quality advice on designing thermal management systems. Our TMS thermal stores and modular auxillary kits are the result of our knowledge, experience and research to date. We guarantee that you will not find a more efficient or effective system at even double the price.

Technical engineer, David Lloyd-Jones, was involved in the design and installation of the largest domestic solar thermal project in the UK and provided the basis for the subsequent BRE government 'Guide for Solar Professionals' and 'Shine 21' installer training manuals. It is very unlikely you will have a problem that we have not already come across and have a solution to. We are also very proud of our Welsh design award for UK manufactured solar pump stations and roof integrated solar collector systems.

Thermal Store Design Process

The first thing you should do is try out our thermal store system builder, where you'll be able to design and price your own modular system - commitment free. The system builder has step-by-step notes that will help you from start to finish, and if you have any questions then please use the comment boxes at the bottom of each section. Once you register an account, a TMS specialist will review your choices and project requirements and it is likely they will recommend that you make some changes.

Our thermal store cylinders are fully customisable, meaning you can choose the rotational positioning of your heat input/output connections, which will speed up and simplify the installation process and ensure a clean compact finish. When you are happy with the system, we require a deposit of £1200, after which you will need to confirm your layout design with TMS. You will receive your cylinder and auxillary kits in approximately 10-12 days after this stage.

Thermal Store Installation

Assembly is much like a Meccano set for adults, which means after learning the fundamental principles, you can do 90% of the work yourself. Using printed instructions and picture diagrams, you will attach each modular kit onto cylinder mounting studs, which normally takes a day or so. Once you've done that, you bring in the plumber to do nothing but run pipe from A-B, which keeps your costs down.

The TMS thermal store is not suitable for anyone looking for a ready-to-install, universal system that just about does an average job. If you are willing to do some basic research, learn and understand how simple and effective a good system really can be, you will not settle for anything less. If you choose to use one of our systems, we guarantee you'll be happy with the results for years to come.
