Pressurized Solar Thermal System Layout
A pressurized solar hot water system almost always follows a standard layout, which is one of the reasons most manufacturers are able to offer simplified kits for residential installations.

Active and Passive Solar Space Heating
In most parts of the world, space heating systems are installed in every home. They provide warmth and comfort during the colder part of the year. Unfortunately, the vast majority of these systems rely on grid-tied, non-renewable power sources to provide that heat. In a bid to reduce our environmental impact – not to mention our operating costs – we can use the sun's power to provide space heating.
Pressurized Solar Thermal System Considerations
If you think a pressurized solar hot water system fits your needs, you must consider a variety of rules, limitations and requirements, as outlined below.
Array and pipe mounting
Collector arrays should be mounted so that there's a slight slope towards the return inlet, where the solar fluid enters, which should also have a drain for maintenance.
Solar Thermal Space Heating Basics
Like solar thermal hot water installations, there are many different options available for space heating. Before you consider them and work out which is best for you, it is important to be aware of the limitations and pre-installation suggestions outlined below.
Pressurized Solar Thermal System Pros and Cons
These systems have many advantages:
Solar Thermal System Check Valves
A check valve is a simple device that only allows liquids to flow through it in one direction. These valves have an arrow marked on the outside to show the allowed flow direction. Two different types are used in solar thermal installations: "spring" and "swing" check valves.
Maintenance of Solar PV Modules
Eliminate Tree Shading
You will want to shade your house's south side from the summer sun, but not your PV array. Even partial shading can cause a disproportionate loss in electrical energy. Trees should be maintained to prevent obstruction, especially between 9 a.m. and 3 p.m. (the prime sunlight hours).
Solar Thermal Equipment: Vents and Vacuum Breakers
All modern solar thermal systems use both vents and vacuum breakers. Vents are used to allow air to escape from a circuit that holds fluid and vacuum breakers do the opposite, letting air in when the internal pressure falls too low.
