It is so very easy to produce hot water using simple and safe technology and this could make a major contribution to the energy crisis and global warming and it is a DIY solution.
The WrightChoice amazing solar thermal system needs no electrician and you can install it yourself with just basic DIY skills to create heat collection efficiencies like to no other system.
Why is a WrightSolar system so low cost.
Our system works with any existing vented cylinder and we use simple hydraulic innovation to make our system totally and irrefutably safe and immune from any danger of over-pressurising the internal or external plumbing in your home. You use your existing unvented hot water cylinder (we will shortly be releasing a system which works with unvented cylinders as well).
How does the cost compare with other systems?
To be as fair as I can, I have compared the cost of my system with the cheapest two panel Screwfix System.
Screwfix System (£2,199.99 + £389.99) £2,590 Excluding Hot Water Cylinder
2 panels (3.7 M2) including roof fixing kits
Solar Discharge Container (6 litre)
Solar Expansion Vessel
Controller and Pump
Solar Expansion Vessel and Connection Kit
15 metres of Solar Pipe (additional £389.99)
TOTAL COST EXCLUDING PROFESSIONAL FITTING SERVICE £3,000
WrightSolar System £400.00 for the Basic Panels & Kit Only. Uses your existing hot water cylinder.
1 lightweight plastic solar thermal panel (4.0 M2) £200 approx
Wright Solar Pumps, Controller, Fittings to connect to your tank and the solar panels, and 30 metres of solar pipe = £200
TOTAL COST EXCLUDING DIY FITTING SERVICE £400 : Uses your existing cylinder
Please note that we will be selling the kit described above for £400 if you want to use your own solar panels.
We are currently awaiting delivery of the controller which will be part of our kit.
Water under pressure in an unvented system is dangerous no matter what safety features exist. When you design a system which never and can never ever pressurise the system, then that risk is removed which is the first principle of prevention.
The system is very easy to install and no electrician is required. Please email me at alanderekwright@icloud.com for further information.
Comparison between WrightSolar and Unvented Solar Thermal
An unvented system needs to be fitted with many extra safety features because the panels can reach super heated temperatures well above the normal boiling point of water and at extreme pressure. You need high pressure solar thermal pipes at £25 a metre. Such systems need to be fitted by a qualified plumber.
WrightSolar Solar Thermal is DIY friendly
We use 12 volt pumps and controllers run from a transformer simply plugged into a standard 3 pin plug socket.
We safely use 10mm plastic pipes rated to 94 degrees C at 3 bar costing 50p a metre.
We use your existing vented cylinder.
This is the simplest of solar thermal and this can be found on this web site.

Direct water heating with solar is very simple , DIY, and low cost, but it can lack efficiency. It is only in direct sunlight in the middle of the day that you are most likely to get water at a high enough temperature to return to this water the top of the hot water cylinder.
WrightSolar Solar Thermal systems can pull water from the bottom or the centre of the hot water cylinder, and they send this water to the panel. Pre-heating the water in the bottom of the cylinder when the sun is unable to heat the water in the panel to a high temperature, allows the water to reach higher temperature with less energy when there is full sun. Water returning from the panel is monitored just before it reaches the hot water cylinder.We select which water to send to which part of the hot water cylinder depending on the temperature of the returning water.
WrightSolar DIY Solar Thermal
In 2010 I developed a solar thermal system which gave me close to 100% hot water from early April to late October and I stored water above 40 deg C for up to 3 days of cloud and rain. This system gave me up to 250 litres in the loft at 85 degrees centigrade and a further 250 litres at 85 deg c in my airing cupboard.
I have installed 500 litre hot water cylinder in in my airing cupboard to replicate my success in a single tank and with traditional flat plate solar thermal panels which were installed on my roof on the 16th May 2022 (see photo).
