Heating Your Pond.

Winter in the UK (and Europe) can be very long and harsh for our Koi, an increasing number of Koi keepers are heating their ponds for the following reasons:
  • Very low temperatures are avoided - causing less stress and associated health problems - Temperature fluctuations are avoided once again causing less stress to your Koi

  • Koi emerge from the long winter into spring considerably stronger and reducing mortality rates at this time of year when they most often occur

  • Your Koi's immune system is not suppressed

  • Biological filter systems remain active throughout the winter months avoiding the long start up process in the spring.

  • Last but not least heating your pond allows the Koi keeper to enjoy their hobby throughout the winter months.

There are many 'So Called Experts' out there that continue to try to tell us 'That it does our Koi good to have a winter' - as I have said so many times... that is a load of rubbish ... and any of these so called experts should not be even advising anybody, least of all the Koi keeper - on the subject of Koi keeping Koi are NOT COLD WATER FISH - they are sub, or even Tropical Fish ... So please don't listen to these so called, self-opinionated, experts !

I have often heard Koi keepers during the winter months say 'Our Koi are Hibernating' .... sorry to disillusion those people but it is 'Hedge Hogs' that hibernate - Koi don't - they just die !

Heating Your Pond
I will pose a hypothetical question to you... 

If you went to your pond in the middle of summer - and all your Koi were huddled together in the deepest part of the pond where they were laying still - some even laying on their sides and not eating anything for weeks and weeks on end - what would you do ? I'll tell you what you would do in a single word 'Panic'-  well why don't you panic in the winter ?- you should ! because you are causing your Koi unnecessary suffering and may cause many of your Koi to die a terrible slow death .. please do not do it ... So Please 'Heat your pond'

We are often asked - 'Is it a complicated or a hard job Heating a Pond or Tank System'?

The simply answer is 'NO' ....  but of course it depends entirely on many factors ....

  • How big the Pond or Tank is ......?

  • Is there a Gas / Oil or Electricity supply to your property .....?

  • Have you already got either a Gas or Oil Fired Boiler .....? 



That is another question that we are often asked ... Well of course 'How long is a piece of string ?'
It is impossible to give any accurate running costs for any heating system - there are many factors to be taken into consideration...

  • How big is the pond.
  • How exposed, or sheltered is the pond - is there a cover over the pond.
  • What part of the World are we talking about.
  • How long is the natural winter
  • What temperatures are required.
  • How far away is the boiler, or electricity supply  

As we have said - these factors, and there are many others, all have to be taken into account 

In England - in our own region - which is known as being a 'Top Coat' colder than the south of England - to give you some idea..... One of our customers who has a 4,000 gallon outside pond which is reasonably sheltered and he maintains an ambient temperature of 56 degrees (12 c) ... He has constructed a polythene cover for his pond using a wooden frame and therefore prevents ice forming on the pond in any event ... and he estimates that his heating costs for his pond is somewhere in the region of 6.00 (sterling) per week .... This based on an average of ...lets say 16 weeks (the coldest weeks covering the Months of - Nov -Dec - Jan - Feb.... would mean that is heating costs for the winter period would be 96.00 .... which is quite reasonable when we consider what benefits our Koi have derived throughout this period from the sustained temperatures .... Another installation that we have done which has just gone through its first winter is an outside pond, again covered, but the actual pipework runs from the filtration house to the pond are in excess of 40 meters, The Pond contains 6,000 gallons and the form of heating system is by way of 'Bottled Gas' as there is no supply of Natural Gas to the site, and its winter running costs for this winter... and bearing in mind the additional costs in the actual gas which is more expensive that natural gas ... has been 10.00 per week ... giving a total heating cost of 160.00 for the 16 week period ... Almost twice the price of the previous pond ... so as we can see no two ponds are alike .... and fuel costs do fluctuate

 So what have we gained by heating the system ? 

Well for a start we have been able to feed our Koi for the whole twelve months of the year so they are getting the full nourishment they require to keep them in good condition - and they are now growing twelve months a year - not just through the summer months - The risk of losing our Koi has been dramatically reduced because we have been able to maintain a temperature acceptable to them ..... Lets face it with the cost of our Koi increasing as it is doing ... it would only take the loss of just a single good Koi to far outweigh the cost of heating the pond ... in fact in many cases it would be considerably less to heat rather than to suffer continued losses of good Koi through the winter months due to the severe cold temperatures of the water .... Because we have been able to continue feeding we still have mature biological filtration - we don't have to go through the process of 'Starting Up' our systems at the beginning of each season ...

So there is no doubt in our minds that eventually we shall all get round to heating our Koi Ponds and tanks .... it need not cost the earth ...... and the overall costs are well worth it !
