Cast Iron Radiators Versus Steel and Aluminium Radiators - What Advantages do Cast Iron Radiators Have Over Aluminium and Steel Radiators

时间:2017-06-10 15:40来源:未知 作者:Kevin
Period Renovations
For period renovations such as barn, church or warehouse conversions and extensions the 
cast iron radiator is certainly the better choice to compliment the age of these buildings 
and provide sufficient heat output to heat these spaces comfortably.
You might be thinking "why would that be?" Cast iron is an excellent conductor of heat 
and therefore works far better in larger spaces with taller ceilings. Although they do tend 
to take quite a bit longer to heat up due to the density of cast iron as a material, once at 
temperature they retain that heat much longer than any other radiator type.
Space vs heat output of Cast Iron Radiators
When considering the space a radiator will take up versus it's heat output - a cast iron 
radiator will take up much less wall space than it's equivalent modern steel or aluminium 
When thinking about this, in order to get the best out of a modern radiator (or any 
radiator for that matter) it needs to be in contact with the air within a room in order to 
heat it and in order to do so needs to be placed in a central location in a room.
When you look at wall space within the majority of houses these central, accessible walls 
tend to be "premium areas" where you want to put things like sofa's, TV's, beds, 
cupboards etc.... and if you have a bed or a sofa in front of a radiator it's not going to heat 
a room space efficiently as it will be pumping all it's heat into the item that's covering it 
and not into heating the room, wasting you money on heating costs and still leaving you 
with a cold room.
So when thinking along these lines, if you can have a radiator that is smaller and not only 
provides the equivalent heat output of one of it's modern counterparts but can also 
become a feature of the room itself, as lets face it the modern radiator is not exactly one 
of the most attractive items in the world, a cast iron radiator could tick 2 boxes in this case.
Customising Cast Iron Radiators
In many cases cast iron radiators are offered custom built to the exact size, heat output 
requirements, colour and in many cases also design for each room space and with many 
companies now emerging into this market, most offer a quick turn around in terms of 
construction and delivery, many within 7 days of order and ready for installation.
The above is not so easy with the more modern radiator as most are available in a set 
number of sizes and in terms of colours, you can re-paint, but the finish is not amasing 
unless you get them sprayed which again comes at an additional cost.
Heating pros and Cons of Cast Iron Radiators
Cast iron radiators have thicker walls than conventional steel or aluminium panel radiators, 
and they also heat up slowly, which in some respects can be a bit of a disadvantage if you 
are wanting to heat a space quickly but as mentioned above they do hold heat far longer, 
giving you more of a consistent and ambient heat output that also lasts a lot longer once 
a heating system is switched off.
As mentioned, steel and aluminium radiators will almost certainly heat a room much 
quicker than a cast iron radiator as they tend to give a quick blast of heat but as they also 
lose temperature very quickly your heating pump and boiler have to work quite a bit 
harder to keep your property at temperature whereas with a cast iron radiator, they retain 
heat for much longer and don't put so much strain on your heating system components.
Cast Iron Radiators and Green Heating Systems
Cast iron radiators are very efficient when coupled with natural heat sources such as Air 
Source and Ground Source Heat Pumps due to their excellent heat conductivity.
Taking ground source heat as an example, due to the density and conductivity of cast iron 
as a material, the heat that is transferred from the ground is held for much longer than 
their more modern steel counterparts, so when the water completes a circuit of heat 
transfer from the ground and into the property, a cast iron radiator will retain a fair 
amount of heat that was generated by the previous circuit, thus the heat pump has less 
work to do
Due to the conductivity of cast iron, the heat transferred into your room is much better at 
keeping them at a consistent temperature giving you a more efficient and comfortable 
What Does all the Above Mean?
Originally, cast iron radiators were seen as the most efficient radiator for period homes 
only, however as we have all become more environmentally aware in the past few years, 
with efficiency being an ever increasing important factor to consider, the cast iron radiator
has enjoyed a major revival in popularity and has become a desirable feature taking pride 
of place in living areas within both the modern and period homes due to their efficiency, 
especially when coupled with environmentally friendly heating systems.
Many contemporary homes today are also choosing cast iron as opposed to modern steel 
as they are both installed in the same manner, they are also space saving, beautiful to look 
at and last far longer than the majority of their more modern equivalents.
Cast iron radiators, with a well chosen colour scheme, can add dimension to a modern 
room and provide an attractive focal point.
As cast iron radiators are still quite a re-emerging product, in most cases they are going to 
be more expensive that your standard steel or aluminium panel radiator but when you 
consider the possibilities of efficiency and the money that can be saved and their longevity, 
cast iron radiators should always be a consideration.

With period renovations the cast iron radiator comes in a choice of different period styles 
befitting the Edwardian, Victorian, Regency or Art Deco home, unfortunately the modern 
steel radiator tends only to compliment the contemporary setting.
Reputable cast iron radiator companies are now offering paint effects to enhance their 
beauty such as antiquing and high lighting detail to compliment historical room decor.
The mindset that cast iron radiators are old school and inefficient is rapidly diminishing as 
today's market is increasingly understanding and experiencing their efficiency and beauty.
