    We have enjoyed giving this service free of charge however ongoing increasing financial costs of running this service is making it increasingly difficult. Up until now we have resisted advertising as a means of a revenue stream to help run this forum but it has become inevitable that extra revenue is required to run this forum.

    We have introduced a donate button to help offset the cost of running this forum. It is completely voluntary, but if you would like to donate, all donations would be greatly appreciated.

    Thanks Murray..

    Hello,

    Heaters are rated in wattage - my question is what is the wattage per gallon requirement in order to heat my system?

    How many watts would you need for a 100 gallon system? 200 gallons? 300 gallons? 400 gallons? etc.

    Hi C, welcome to the forum.

    One watt per litre of water is a general rule of thumb that works well here in Perth winters to maintain systems at 20ºC+, but it may vary depending on your local ambient air temp etc. Our nightly minimums in winter are usually between about 5ºC to 10ºC, with the occasional 0ºC
