Inline Water Heater
Inline water heater, another term for tankless water heater, is relatively new to the United States but it has been widely used in Europe and Asia for decades. With today's environmental concern and economic condition, using a tankless heating system would be a practical move.
Inline water heater does not need a storage tank. It only heats the water on demand, thus heat is not wasted. The water is heated as the water flow sensor senses the flow, turning on the heating elements. Water is then heated to the desired temperature, giving you endless supply of hot water for domestic and commercial use. And when the tap is switched off, the heating stops and your machine is ready for the next use. This cuts your water heating cost by up to 50%.
Tankless heaters can be electric or gas fired. Electric type heater is easier and safer to install because it does not require venting and does not pose a carbon monoxide risk. The gas-fired inline heater, on the other hand, which may use natural gas or liquid propane, has the advantage of delivering greater volume of hot water output. So depending on convenience and preference, you may opt to choose one over the other.
The point-of-use (POU) and the "whole house" are two types of inline heaters in terms of the volume produced. The point of use is a smaller unit which is able to supply one or two hot water outlets at time. While the whole house is a bigger unit designed to provide hot water for bigger households with simultaneous use of multiple hot water outlets.
Inline heaters are eco-friendly machine. Using them reduces tons of carbon dioxide emission each year, decreases the number of non-biodegradable storage tanks thrown in land fills, and decreases the dependence of non renewable resources such as the natural gas.

Ductless Heat Pump Facts and Figures
These days, watching your spending is a big deal. The economy has taken a big dip, but this is not always a bad thing underneath the surface. The economy has opened many people's eyes to the more important things many of us have overlooked. For many, the recession has shown them ways to generate money from their current infrastructure by changing things that are incredibly inefficient such as their boilers and heating resources.
Spending too much on inefficient boilers, heaters, and heat pumps is something more than a rational amount of people have simply taken for granted thus felt powerless to change it. With the economy forcing people to find ways to save money, many have revisited the main drains on their wallets. For many whom are using electrical heat generating concepts, a simply change to gas, oil, or the ductless heat pump can bring a significant amount of savings.
The economy will bounce back eventually, and although many suffered the wrath of the recession, they will no doubt come out of this ahead. The money you can save, for example by using a ductless heat pump over a duct system could be significant as you may come to realize that you can get the same heat without all the extra unnecessary equipment. If the ductless unit will produce and distribute the needed heat without first pumping it into the ducts and losing all that heat that gets trapped up there, then you will have gained a better posture and a more efficient system- not to mention a much cheaper way to go!
For many, their current system was there when they moved in and they never questioned weather or not it was overbearing, or inefficient. Today, these same people who would have never taken a second look are now experimenting and learning that there truly is a better more efficient, less expensive way. The same goes for people building on their current foundation.
If your home uses a duct system, an electric heating concept, and you add a room or a new wing to your home, chances are you will add more ducts to append the current system. This may not at all be necessary, in fact if it's too far away from the heating source, this may be a bad idea. Using a ductless heat pump in this room may be far more effective, less expensive, and requires no additional expense putting in the ducts!

Solar Hot Water - How Does It Work?
Solar Hot Water
A lot of folks out there think of one thing when they hear the term "solar power". They think of electricity. Actually, two kinds of solar power exist - solar electric and solar thermal. Solar electric uses photovoltaic (PV) panels that transform light photons to electricity. Solar thermal heats water.
Solar thermal has many uses. It can be used to heat the water that is used for showers and laundry. It can be used in a radiant heat system to heat floors or living spaces. It can also be used to heat swimming pools.
How Does It Work?
There are many different types of solar thermal systems, so for the sake of simplicity we will discuss a simple drainback system. This system consists of solar collectors, a heat-exchange tank, a pump, and a controller. Solar fluid - in this case, tap water - resides in the heat exchange tank (that looks like a traditional hot water heater) and is pumped up to the solar collectors on the roof (or wherever the panels are located - they do not HAVE to be on the roof). The collectors have hundreds of feet of tubing inside them in which the water is circulated. When the sun shines on the solar panels, the water in the tubes in the collectors gets very hot and returns to the solar heat exchange tank. The domestic water is pumped through a coil of copper tubing and this coil is inside the solar heat exchange tank. The heat from the water in the tank is transferred to the potable water in the coil of copper tubing, heating the domestic water that is later used for household processes.
Solar thermal has a much quicker payoff than solar electric - usually 5 to 7 years. It is especially effective where a large concentration of people reside, like a dormitory, fraternity, sorority, or even a jail. These examples tend to be the most popular installation sites for solar hot water systems. The system configurations for these types of locations usually consists of one 120-gallon solar heat exchange tank with a pump and controller, and four or five 4' x 10' solar collectors.

The Model SH-22 four-chamber tank less electric space heater is designed for usein residential and commercial hydronic space heating applications such as, but not limited to, radiant floor heating, baseboard, hydro-heat pump and snow melting systems. This new micro-boiler is the ideal replacement for traditional boilers and tank-type heaters and is the enabling technology for use with active renewable energy systems such as solar and geothermal systems. The temperature activated control works effectively in low pressure and re-circulating systems. With optional equipment, the SH-22 can be used as the single heat source in combination systems for potable hot water and space heating. A minimum of 200 AMP whole house electrical service is recommended.
