Boilers

2010-01-29T04:08:00.000-08:00

You may be considering replacing your boiler - especially with the new Boiler Scrappage Scheme giving you up to £400 cash back on price of your boiler (for eligible boilers being replaced). If you're lucky enough to be in this category, but want to keep your Hot Water Cylinder, then we recommend that you take a look at SYSTEM boilers from the following manufacturers:

Vaillant Boilers
Halstead Boilers
Worcester Boilers
Main Boilers
Biasi Boilers

Whichever manufacturer you choose, you will want to opt for a System Boiler. Speak to your Gas Safe registered installer to find out more, but remember to ask him to list the cost of the gas boiler in his quote to you. Try to get 3 quotes from installers recommended to you by friends and family.

INDIRECT The Indirect model features a coil with a large surface area at the base of the unit, giving very fase recovery times on the full capacity of the unit. These fast recovery times combined with the foam insulation help to make the range energy efficient.

Been looking for an Expansion Vessel Calculator?

2009-04-15T02:24:00.000-07:00

From looking at the stats for this particular blog, I notice that lots of people surf in here trying to find an expansion vessel calculator.

I've written to a chap who has developed an online Expansion Vessel calculator. I'm hoping he'll let me integrate it into our UK websites and re-word it for the british market (the US market calls a hot water cylinder a 'hot water tank' - not too much of a problem, but always worth changing.

In the mean time, if you're looking for a calculator, then try this one out. I haven't had a chance to get our technical manager to test out the accuracy of the calculations, but any professional plumbers' feedback would be appreciated, so please do drop us a line...

What about Solar Heating?

2008-12-30T05:13:00.000-08:00

Solar heating systems primarily use energy from the sun's rays to warm water in conjunction with your normal water heater. Solar energy is used to supplement your standard method of heating, thereby reducing the amount of fossil fuels burnt in heating your water.

There are three main parts to a Solar hot water system.

A Hot Water Cylinder, suitable for Solar heating. To allow you to have sufficient water heating, you should choose a Twin Coil Solar Cylinder, so that one of the coils warms water by Solar means, whereas the second coil relies on conventional heating to bring your water to adequate temperature.

A heat transfer system which is used to collect the heat to heat the cylinder.

Collectors fitted to your roof or in your garden, in a suitably uncovered spot. In this case, we are talking about solar heating panels and the relevant parts. You could consider Ground Source Heat Pumps, or Air Source Heat Pumps as an alternative to Solar panels.

Solar panels are not intended to replace conventional methods of water heating, but they can deliver about a third of your needs. In particular this means that you could save at least £65 per year in water heating bills. A typical installation will cost between £3000 and £5000. These systems require very little maintenance, so should deliver savings in 20 years as a minimum. Don't forget the warm glow you'll get from knowing you're reducing your carbon footprint. Include these changes with other energy-saving schemes and you could very well qualify for a low carbon building programme grant funded by the BERR, reducing your time to recover costs greatly.

As solar systems become more popular, many new developers are considering them as part of the standard build. The more energy-efficient a house is, the easier it will be to sell.

What is an expansion vessel?

2008-12-24T01:20:00.000-08:00

An expansion vessel (sometimes called a Membrane Expansion Vessel, or MEV) is a small metal tank designed for closed (or pressurised) heating systems to help absorb any excess pressure in the system, caused by hot water expanding, or water hammer, thereby relieving the pressure in the plumbing system, which could cause expensive damage.

The vessel has been divided into two parts. What separates the two halves is a rubber diaphragm, or membrane. On one side of the diaphram, the expansion vessel is connected to the heating system pipework and contains water. On the other side of the vessel, there is air under pressure (equal to the pressure of the water on the other side). There is a valve on this end to add air and check the pressure inside the vessel.

It's important to keep the correct pressure in some heating systems. When the heating system is running at the lower end of the working pressure range, the air in the sealed (valve) side will exert additional pressure and force some of the water into the system.

As water in the heating system expands (which it will do, when heated), the diaphragm moves the other way because the water on the other side of the membrane is at a higher pressure than the air on the other side. You will see a change in pressure on your pressure guage.

Wherever a tank is needed in a water system, you will usually find an expansion vessel. They are found in Solar Heating systems where a liquid carries heat from the collector to the storage tank.

What is the difference between Direct and Indirect Cylinders?

2008-12-03T06:16:00.000-08:00

The direct heating sytem is heated via the electric elements provided with most current cylinder

The indirect system is heated via a copper coil inside the cylinder by the boiler or an outside heat source (i.e. Solar). This does not include Back Boilers.

Hot Water Cylinders Explained

2008-11-20T04:36:00.000-08:00

Although combination boilers are becoming the norm in new-build properties, there are plenty of homes in the UK that still require a hot water cylinder to supply warm water to taps around the house. Additionally, solar heating panels are now becoming so efficient that you can realistically heat for your home's water needs without calling on gas or electric to provide the energy source.

The jargon can be very technical, so here's a breakdown in as simple terms as I can explain:

Direct Cylinders

These are cylinders that contain some method of heating the water inside the cylinder. This could be an electric immersion heater.

Indirect Cylinders

These are cylinders that get their heating energy from somewhere outside the cylinder. In most cases, this will be a boiler - such as a gas boiler or oil boiler, a conventional Aga or another solid fuel burning stove or from a solar panel. The water inside the cylinder is heated using a heat exchanger, which will transfer the heat from the water inside the coil (that comes from your boiler or other external heat source) to the water inside the cylinder.

There are other types of cylinder that you can buy, but these are usually specific to the heating requirements in the home. The only way to know if you need something else it to give our customer service team a call.

What is mains pressure?

These units allow you to connect the Ultrasteel directly to the mains via the safety valves provided. This allows you to have power showers without the need for noisy shower pumps and means no cold water cistern tanks are required in the loft.

Ease of installation

The unit comes with a full, easy-to-follow fitting instruction booklet and all the components you will need. All the connections are at the front of the unit within a 90o arc. The unit can be sited almost anywhere, including the garage.This gives you the added advantage of 100% usable hot water and means that possibly a smaller sized unit can be used to achieve the required literage.

Duplex stainless steel hot water tank for ultimate
peace of mind

The Ultrasteel is manufactured from highest quality Duplex stainless steel. Care must be taken not to confuse this high performance metal with the inferior grades employed by some of our competitors. This type of steel is far more resistant to corrosion than glass lined models and therefore offers a much longer life. Consequently, no anode is required. Duplex stainless steel provides for a much lighter and easier to handle unit.

High flow rated controls deal with multiple hot water applications

Our standard valves offer exceptional flow rates and deal with most domestic applications. Larger valve options are also available for industrial and commercial use by special order.

Fast reheat and thick insulation means
cheap to run

The coil is designed to heat the whole of the cylinder contents and sits very low in the base of the unit (unlike conventional coils). Add to this the coils large surface area and a very fast recovery is achieved on 100% of its volume. High heat retention is then achieved by use of 50mm thick
CFC/HCFC Free (ODP ZERO) lagging.
Reasons for external expansion

When developing Ultrasteel, we drew on all our group’s experience of previous unvented products we had manufactured. Earlier mains pressure
units included both internal and external expansions and, with this knowledge, we have listed below our reasons for having no hesitation in going with an external system.

Unvented cylinders with Internal expansion are known by the trade as “bubble tops”. This is an apt description as they do indeed trap a bubble
of air in the top. As the cylinder is heated up, the expansion of the hot water is taken up by the bubble.

As you probably know water under pressure absorbs air. Some people will be familiar with milky water coming from their taps. The milkyness is
the bubbles in the water formed as the air is released.

In some areas of the country, local conditions have led to some bubble top unvented cylinders losing their bubble prematurely. This has been
disruptive and costly for all concerned. Indeed, some have even been converted to external expansion to solve such local problems.

If the air bubble is lost, it is usually necessary to drain down the unit and refill it. As anyone with a water meter will tell you, refilling it costs money
and then the additional inconvenience of having to pay to heat the water again. You would be even more upset if you had to find and pay for a
plumber to do this for you.

Contrast this with the rubber diaphragm inside our expansion vessels. This diaphragm separates the water from the air - PROBLEM SOLVED.
The pressure can easily be checked and topped up with a foot-pump without losing a drop of water.

Add the additional flexibility of remote sitting that an expansion vessel brings and the choice for us was clear - External Expansion.
