For a few years I noticed family and neighbors buying new stuff when something would break down. I actually have a neighbor who traded in his new car when it needed brakes after 18 months of owning it. I actually thought he was joking when he said it. Then the new depression hit, and people did not have the money they used to. All along we have been saving our money by repairing things when prudent. I have been calling the same appliance repair in Sacramento since we moved here. Over the years they have fixed our washer, dryer, dishwasher, refrigerator, stove and oven and upright freezer. We actually have two freezers. One is a chest model and it has been running great for over 20 years now.
The other day I got into our files and looked at all the repair costs we have had for our major appliances. (more…)
Heat pumps use the same technology to heat water as is used to heat rooms. Heat pump systems only use electrical energy to ‘move’ the heat – they don’t actually ‘make’ heat. This makes heat pump systems much more efficient than traditional electric or gas water heaters.
A well designed and installed system uses less energy than standard electric cylinders.
Heat pump water heaters can work in places that aren’t good for solar water heaters – places that get less sun like the south side of hills.
Some heat pump water heating systems can also give you ‘central heating’. They do this by pumping warm water from the hot water tank around a system of underfloor heating pipes. Some other systems
Most homeowners who have heat pumps use them to heat and cool their homes. But a heat pump also can be used to heat water — either as stand-alone water heating system, or as combination water heating and space conditioning system.
How They Work
Heat pump water heaters use electricity to move heat from one place to another instead of generating heat directly. Therefore, they can be two to three times more energy efficient than conventional electric resistance water heaters. To move the heat, heat pumps work like a refrigerator in reverse.
While a refrigerator pulls heat from inside a box and dumps it into the surrounding room, a stand-alone air-source heat pump water heater pulls heat from the surrounding air and dumps it — at a higher temperature — into a tank to heat water. You can purchase a stand-alone heat pump water heating system as an integrated unit with a built-in water storage tank and back-up resistance heating elements. You can also retrofit a heat pump to work with an existing conventional storage water heater.
Heat pump water heaters require installation in locations that remain in the 40º–90ºF (4.4º–32.2ºC) range year-round and provide at least 1,000 cubic feet (28.3
It is always something of course and it seems like my money saving plans have been set back again. I assume that one of the kids put something down the toilet that should not have gone down it. At any rate we had to find someone who did drain cleaning in Hudson county, NJ and pay them to fix the problem. It did not take that long for them to do, but of course it was still expensive in that it took away money I was sitting aside for a big project. You are always going to run into different things though, that is why when you make a plan it needs to be flexible. (more…)
Like every other technological aspects, electronic gadgets have also undergone huge changes in the last few years. It will certainly not be an exaggeration to say that modern electronic appliances have turned more intelligent and are also easier to use. From communication to healthcare, from education to security, nowadays electronic equipments are widely used in every field. This increased use of electronics has led to the development of more and more sophisticated gadgets that can execute more than one task at the same time. Certain electronic instruments are also used as testing and measuring equipment that are now used in different industrial sectors as well as for household purposes.
The importance of electronics
Electronics have become an important part of modern life. Today almost all the appliances that we see around us use electronic parts to some extent. The main advantage of using electronic parts is that they make industrial processes easier and fast, that also with less error margin. Electronic equipments like computers have become an indispensable part of modern life. As the demand for electronic gadgets is steadily growing all over the world there is enough scope of earning huge profits by trading in electronic appliances.
Electronic testing equipment

Researchers at the Université du Québec have recently conducted a survey of four Canadian cities to determine the economic feasibility of installing geothermal heating systems in homes in Montreal, Halifax, Vancouver and Toronto.
For their analysis, the researchers used RETScreen, a free clean energy software package developed by the Canadian government, along with the typical energy considerations to determine the financial savings from the heating systems over the course of 22 years. The vertical closed loop heating systems, in which vertical pipes run into the ground, were proposed for use in both space heating and cooling and to provide 25 percent of the total amount of domestic hot water. The researchers found that the systems would be most feasible in Halifax, with fewer potential savings in the other cities.
“It’s do-able in Halifax because the people in Nova Scotia tend to heat with heating oil, which is relatively expensive at this time,” said Yvan Dutil, a researcher at the Université du Québec’s public engineering school, École de technologie supérieure (ÉTS) and now tutor at the Télé-Université. “In Toronto and Vancouver, however, the natural gas heating source is ridiculously cheap.”
Conversely, Montreal was ruled out because it already receives 99.7 percent
There are few appliances dumber than an electric hot water heater; it uses energy made from boiling water to run turbines to turn generators to be distributed over wires…to boil water again. The AirTap is a heat pump that improves the process somewhat, by taking energy from the air and using it to heat the water. Like most heat pumps, it is advertised as having a COP (coefficient of performance) of up to 3.5 times that of a straight electric element. It seems like a good idea, but is it?
Let’s look at their claims. First of all, the issue of the COP. A heat pump is efficient because it moves heat, rather than making it. But the heat has to come from somewhere, so if you are paying to heat your house, then you are heating the air and the heat pump is removing the heat and sticking it into the hot water. It isn’t free; you are essentially running an air conditioner inside your house and exhausting the heat into your hot water tank. So the unit makes no sense in any part of a country where the heating degree days outnumber the cooling degree days, and certainly makes
