Boilers

Archive for the ‘Electric Boiler’ Category

Most homeowners would love to lower their utility costs and household expenses, and if they could do so while helping to slow global warming and reduce their own “carbon footprint” all the better. These are the primary reasons that many people seek out alternative energies from the sun, wind or water.

Today, millions of homeowners enjoy a remarkable amount of financial relief through the installation of solar panels that collect and generate energy as well as provide domestic hot water supplies. To date, there is no single all-encompassing application that provides a single alternative energy answer to the numerous systems throughout any home – just as there is no single traditional energy answer for an entire home.

While there are currently no solar technologies that can completely eliminate a home or property owner’s need for traditional electric or utility suppliers, there are several systems that can be incorporated into a home or building’s existing systems to help reduce emissions, cost and energy consumption.

One of the simplest systems to address is the domestic hot water supply. To incorporate a solar water heating system into an existing or conventional system requires three essential components: solar panels or collectors, a transfer system, and an appropriate hot water cylinder. Generally, it is suggested that a professional install, or at least design, the system to be utilized. This is because a solar water heating system has several factors to be considered before being purchased and installed.

First, an ample supply of southern facing roofing must be available to meet the needs of the required system. Generally, evacuated tube systems will require significantly less roof space than the more traditional flat plate systems. Next, the existing system must be analyzed in order to see if it is suitable for a second solar water-heating boiler to be added. Currently, most combi boilers are not suitable for any solar water heating systems to be incorporated. Finally, budgetary concerns must be addressed to select the most affordable system for a homeowner’s financial capability.

Financially, the “average” installation of a solar water heating system can save a home or property owner a significant amount of their annual fuel or energy expense and should be figured into the cost of purchasing and installing a solar heating system.

Today, most solar water heating experts in the United Kingdom recommend the installation of evacuated tube systems. They are doing so for several reasons. First, the evacuated tube systems operate at much more effective levels under low-light and cold weather conditions. Because this is a frequent pattern in the United Kingdom the more reliable function of the evacuated tube systems are making it the preferred installation. Secondly, the evacuated tube systems require a lower amount of space for equal performance, which adds to the aesthetic as well as functional value. Finally, evacuated tube systems have very limited maintenance required and they do not allow for some of the traditional problems of flat plate panels which can frequently suffer from standing water and broken seal conditions.

Are your energy bills too high? Is your home not as comfortable as you want it to be? Do you want to do more to protect the environment? Do you have teenagers at home giving your hot water bill a beating? Whatever your situation, this will help you to find a solution that’s right for you. This guide is primarily aimed at homeowners who are thinking of upgrading or replacing their home’s existing heating or cooling systems. It also contains useful information for people who are having a home built for them, and for those who want to reduce their energy consumption in general.
 
While builders generally offer a standard heating or heating/cooling package, upgrades to more efficient equipment might be available.Always have them system inspected after installation so proper codes with the different systems, fuel options. Remember to also ask your builder about other energy efficiency upgrades, which can range from extra insulation to a complete R-2000-certified home. Before being R-2000-certified, each home is evaluated and tested to ensure a high level of energy efficiency has been designed and built into it. There are both financial and environmental benefits to conserving energy and using it wisely. To help you conserve even more, this will also direct you to resources that can help you reduce energy consumed for purposes beyond heating and cooling your home.
 
A Wise Choice
 
The options presented will help you to select heating and cooling systems that meet the needs of both your lifestyle and your check book. Besides the obvious savings for you that occur by lowering your consumption, by reducing demand for energy through conservation or, in the case of electricity, even from shifting consumption to times of lower demand, together we can lower the market price for the energy that is consumed. The advantages of investing in energy efficiency aren’t only felt within your family budget– they are realized in the cleaner environment that goes hand in hand with more efficient systems and the wise use of energy.

Before You Start
 
Putting an energy-efficient heating system into a drafty, poorly insulated house will not lower your energy bills. But you’ll notice a more dramatic increase, and even create even geater problems.If you want to make your entire house more energy efficient. How? Let a atlanta home inspector do a affordable energy efficient inspection.

• Weatherstrip and caulk to seal air leaks. You may have to replace uncontrolled sources of air with designed sources to ensure proper ventilation.
• Increase insulation levels where appropriate (such as in the attic or walls) to reduce heat loss in winter and heat gain in summer.
• Open drapes on south-facing windows on sunny winter days so that the sun’s energy can help heat your home, and close them in summer to help keep your home cool.
• Choose energy-efficient products when replacing windows and doors.

By making your house more energy-efficient, your heating and cooling systems will work less, and you may reduce the capacity needed when you replace your systems, which means more savings for you.
 
Why Energy Efficiency Matters
 
It’s good for your budget, your comfort and our environment. Each year you spend hundreds of dollars to heat and cool your home and to heat your hot water. By installing energy-efficient equipment, which gives you the same comfort for less energy, you can lower these costs. Furthermore, the lower you can make your energy costs now, the better off you will be should energy prices go up – and conservation reduces upward pressure on energy prices.
 
Whenever fuels are burned – in your home, in a generating station to produce electricity, in vehicles or elsewhere – carbon dioxide, nitrogen oxide and sulphur dioxide are released. These emissions contribute to environmental concerns including smog, acid rain and climate change. Reducing energy use lowers the amounts of these emissions and their impact on the environment. You can help by practicing energy efficiency and conservation not only in heating and cooling your home, but everywhere at home, in the workplace and in your transportation choices. Many factors can affect your annual energy bill such as size and location of your home, yearly variations in weather, efficiency of your furnace and other appliances,

thermostat settings, number of occupants, and the local cost of energy.
 
Are you serious about how to go about cutting your heating and cooling costs?
 
Follow these steps:

• Where appropriate, improve the insulation and air sealing in your home.
• Use this guide to help you decide what kinds of changes to your heating and cooling systems will be right for you.
• Consult with a registered heating/cooling contractor and your fuel supplier before making a final decision.

Heating Units and Controls

There are four common types of heating units:

• A furnace provides heat through a forced air distribution system.
• A boiler provides heat through a hydronic distribution system. (Hydronic systems are also referred to as hot water systems.)
• A space heater supplies heat directly to the room where it is located.
• A heat pump extracts heat from the air, ground or water outside the house and usually delivers it through a forced air distribution system.

Most heating systems need air for combustion. Furnaces, boilers and space heaters that burn fuels need a supply of air to be able to burn properly, and a vent to the outdoors so that combustion gases can escape from the house. Electric heaters do not need to be vented. Combustion is a two-step process: air in, and gases out.
 
Air in
In the past, there was usually plenty of air leaking into a house to keep the furnace, boiler or stove burning well. Modern homes, however, are better sealed and use controlled ventilation, rather than uncontrolled leakage, to provide greater comfort and energy efficiency. Vents that supply air for heating units should never be blocked. It is important to ensure that there is an adequate supply of combustion air available, even when other air exhausting equipment is in use.
 
Gases out
Venting used to be done through a chimney. Today, however, many models of natural gas, oil and propane equipment can be vented by pipe directly through the wall, which greatly simplifies
installation. Remember that combustion gases cannot escape from your home unless you provide air to replace them. That’s why venting problems can often be traced to air supply problems.
 
Controls
The indoor temperature is automatically controlled by a thermostat. Two important considerations are location and type. Central systems are normally controlled by a single thermostat. To achieve proper temperature control, the thermostat must be located in an area where it will sense the “average” indoor temperature. Locations exposed to localized temperature extremes (outside walls, drafts, sunlight, hot ducts or pipes, etc.) should be avoided.

 
Different types of thermostats are available. Basic types maintain a fixed indoor temperature. However, you can reduce your heating costs by installing a set-back thermostat which can be programmed to automatically lower the temperature when no one is home or everyone is in bed, and then warm up the house before you get home or wake up. Savings will vary, but a set-back of 3ºC for eight hours daily could reduce your heating costs by about 5%.
 
Where space heaters are used, each unit will likely be individually controlled by its own thermostat – which is usually the basic type. This allows you to keep unused areas at a lower temperature than those areas you do use.

i own a small studio flat, looking at getting about 5 rads fitted on a wet sytem, currently running hot water via cylinder in cuboard and cold water from loft tank directly above, so really poor water pressure.
Really looking at getting best value for money and how much it might cost to get the work done.
Thanks,

Hi BOTY.
Turdy spelt it out perfectly for you.
Electric Boilers do cost more to run…..but.
They don’t have to be serviced every year.
They are completely silent.
You can fit them anywhere in the house.
No flue is needed.
They won’t blow up and flatten the neighbourhood.
You won’t be killed by CO. fumes.
They don’t go wrong.
They are ideal for small flats.
As for cost, the only answer is to get three estimates from reputable companies.
You are definitely on the right track.
Make sure that you go for the economy 10 option.
