Hot water solar collector tube work or not in UK weather?

Hot water solar collector tube work or not in UK weather?
Could you give me some advice please. I want to know about the solar collector evacuated tube. Are they strong enough? I heard that some of this tube are explode or break when it get very hot. I want to know how reliable they are. Are they work in UK weather or not or is it a waste of money, because most of the time is cloudy. If it does work how many tube require to heat 210 litres water cylinder

this is what i do for a living.

Yes evacuated tubes etc WILL work,BUT flat plat panels are just as good these days. The problem with most tube design is that they are self limiting at a relatively low temp, so in the summer they will "switch off" once they reach a certain temp, where flat plates will keep transferring the energy to your water until it reaches a programmed cut off which is quite high but safe.

There was a few cases of tubes exploding when they got too hot, not heard about that for a few years now though, problem seems to be fixed. Tubes only last (usually) 10 years, where flat plates will last 25+.

2 flat plates will be good for 210 L AND won't need replaced!

SOLAR HOT WATER 2 DIY USING BLACK WATER HOSE SOLAR WATER HEATER SUN POWER

Solar Hot Water

Solar Hot Water is the H2O heated using energy from sun that is Solar Energy. As you may have noticed that the shallow water of a lake is warmer than the deep water because the sunlight directly heats the lake bottom in the shallow areas. In the same way, sun can also be used to heat water in buildings and swimming pools. The solar heating systems is generally used to heat water for home, business and industrial usage. Hot water heated using sun's energy helps in generating electricity and can be used for sanitary purposes such as showering and washing.

Solar hot water systems are storage systems that can provide up to 90% of your hot water for free. In smaller households or in cooler parts of the country solar systems may be less appropriate depending upon climatic conditions. Solar heating systems is composed of solar thermal collectors and a fluid system to move the heat from the collector. The system have tank for heat storage. Solar hot water systems use flat-plate solar collectors that are typically installed facing in south direction on a rooftop. The collectors are made up of simple glass topped insulated box containing a flat sheet metal solar absorber attached to copper pipes and painted black. To heat water using sun's energy, a collector is secured on wall facing the sun. The most common solar water heating systems are active systems. Active systems contain pumps to move the liquid between the collector and storage tank whereas, passive systems rely on gravity.

Rheem is one of the leading US manufacturer of solar storage tanks. It is basically used in residential solar water heating applications. Solahart is also a Rheem company since 2002, manufacturing solar water heating systems and collectors for over 50 years and most trusted in United States.
