Will these closed solar panels be able to heat a medium hot tub when the outside temperature is 40 degrees farenheit?

The best information i have found exactly here. Keep going Thank you

How can I build a closed loop solar system and not have it overheat in the summer when I go on Holidays?

Solar Home Heating-  This topic receives the most enquiries from our customers.  As such I thought I might expand on this subject an open up a new blog topic dealing with solar home heating.

Solar home heating is very feasible especially with our TZ58-1800 30R heat pipe collectors that operate with high efficiencies in the winter even at minus 40 they produce hot water!   When desigining a home heating system in freezing climates you will need to use glycol water mixture as you heat medium and use heat exchangers to transfer the heat to your home heat source.  

You can integrate solar heat with an existing water boiler or an infloor heat system simply by placing a heat exchanger before the return supply line.  In this way the solar acts as a pre-heat, heating the water before it enters the boiler reducing the amount of energy the boiler must supply.  A home heat system can also be used by placing a heat dissipator (air to water heat exchanger) in the return duct work on a forced air furnace.  What ever type of heating system you have solar home heating can be integrated as a supplement.

A home heat system should always be used in conjuntion with another demand zone such as domestic hot water or solar pool heating.  This allows you switch zones to avoid over heating and manage your supply and demand.  Our SDS with the Resol BS/plus controller is ideal for a two zone home heating sytem.

An average 1600-2000 square foot home will require about 4 x TZ58-1800 30R collectors and a complete system with domestic hot water zone will cost approx $8500 with two zones.  However the payback can be substantial and a home heating system is elligible for the federal grants which can further decrease the payback period.  When comparing paybacks to other heating sources such as Geo Thermal, solar heating has a significant advantage in that as energy cost rise, its payback gets shorter.

Can Vacuum tubes replace my old leaking rubber solar collector? This will be the 2nd time I have had to replace it in 7 years and I am looking for a better pool heating solution. Seems like you might have what I need?

How good are the themal heat systems in our latitude and how is the solar collecters in winter?

What Kind of Insulation should I use for my pipes in our solar hot water system?

I have a great spot on a south wall to mount collectors. Is a wall mounted sollar collector recommended. My roof runs east west and I know this is not as ideal as south facing solar heater.

Thanks in advance!

I like your design on a solar storage tank conversion using an electric tank, this makes alot of sense and seems like it will save us at least a $1000 versus buying a specific “solar pre-heat” tank. I live in Texas, do I need to use a heat exchanger? It almost never freezes here.

Thanks
