For all of these home improvements, the best way to see if they make sense in a cost/ benefit analysis is to talk to an energy rater. This person can determine how much money you will save over the course of a year by plugging numbers into a computer program. This will help you decide if it makes sense to make the investment. If you will save 0 per year for the next five years, and it costs 00 to install a system, then it's definitely worth it, even without the tax credit to boot.
New homes, well built, require little maintenance. The older the existing home, the greater the maintenance that is needed, whether you tackle these jobs yourself, or hire someone to do them for you. This includes attending to hot water services that may be antiquated, spouting, roofing and decking. When a good builder puts it in place new, then you will have no headaches about any of these areas.
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.
Here is a list of just some of the things a professional plumber can do for you: install or repair gas or electric water heating, install hot water circulating pumps, fix kitchen, bathroom and other faucets, install a garbage disposal or water purification system, install or replace shower heads, install a drinking water or instant hot water device, flush out valves, clean and repair or replace pipes, install or repair all kinds of toilets. The list goes on and on. If it has to do with water, your plumber can handle it.
A good plumber will be on call 24 hours a day. Plumbing problems can spring up any time of the day or night. You don't want to have to wait until the next morning i your toilet starts overflowing or a major pipe bursts in an apartment upstairs and you have to turn off the water in the whole complex.
For long pipe runs the low flow fixtures result in more barely-warm water from the hot water plumbing to be run down the drain. That means you are running heat energy down the drain too. That is wasting energy and costing you money.
Any way you look at it, installing solar cells is going to be worth the effort. You are providing a source of renewable energy that will last in years to come. You are helping the environment by using less energy for electricity and lights. Because you save up to 30%25 of the investment in the form of a tax credit, you only need to save the additional 70%25 of the cost over time to make it worth while. This doesn't usually seem to be a problem for many homeowners, especially given the increasing costs of energy, especially electricity. One thing to keep in mind with PV's is that PV's can have batteries that can be used as a backup if the sun didn't offer enough energy for a certain energy need.
