If none of this works, then you must be facing a major plumbing problem, and a plumber may have to be called for to rectify your problem. Plumbers are professional who will know where exactly is the problem and how to deal with it. But when you call in a plumber, make sure he is reputed. It would be better to employ a plumber recommended by your friends or relatives and It would be better to use a licensed plumber who knows the job well.
Solar Thermal is mostly used to heat water. There are several different types of Hot Water Systems and any Solar contractor in your area can tell you what type of system is right for you. Typically a Solar Hot Water System can save you 50%25-90%25 of the cost to heat your water. It also carries a 30%25 tax credit and in my opinion it is the best place to start when considering Solar.It saves you money, and the return on investment is far better than any savings plan available today. These systems will last 20 years. They are paying you money back long after they have paid themselves off.
There are other manufactures that make similar systems such as Grundfos, RedyTemp, and Watts, with some variations but basically the same luke-warm type of hot water system. Again these systems won't work with tankless water heaters and run anywhere from 0.00 to over 0.00.
Depending on your plumbing layout these units can often supply quick hot water to more than one sink, and sometimes all of your sinks. You can easily find out how a demand system will work for your plumbing layout. When your pipes are all cold, like the first thing in the morning, just pick the location you think is the furthest from the water heater and turn on the hot water until it gets hot.
If you happen to turn on the hot water faucet when the hot water has cooled down almost to the set point but not quite, your hot water will actually feel cool to the touch. and you will have to run luke warm water down the drain until the hot water arrives. Now you are wasting energy and water at the same time.
The major problem with hot water services is valve expansion and dislocation, which affects the water supply. In this kind of case, be sure to locate what caused the problem.
Another advantage is that you don't have to deal with dust anymore. Hard-to-clean spaces under traditional radiators are no longer a problem. What's more, your home looks wonderful; you don't have to stare at ugly traditional heating radiators any more.
For basic cleaning, 1500-1800 psi is good. This is more than enough to remove dust, dirt, spider webs and pollution. This is also a good pressure for removing mold when a cleaner is used.
