FAQs
More answers on our FAQ page.
How loud is it?
A machine makes 70–80 dB, about the level of a busy street or a vacuum cleaner close up. Distance, careful siting and aftermarket noise kits bring that down to about 40–45 dB at the vent. See Airflow & Noise Management.
How much power does it need?
An S21 Pro+ or S21 XP draws about 3.6 kW, or 86.4 kWh a day. An S19K Pro draws about 2.8 kW. If you’re not sure your supply can take it, talk to us before you buy.
Which machine should I buy?
For most sites, the S21 Pro+ 245TH. It offers the best balance of price, efficiency and future-proofing for the 2028 halving. The S19K Pro suits genuinely free, part-time power, and the S21 XP gets the most from every kW.
How much looking after does it need?
Two minutes a day on your pool app, fifteen minutes a week on site and an hour a month on filters keeps most sites healthy.
Can I use the heat?
Yes. A machine gives off almost all the power it draws as warm air. One S21 gives off about 31,500 kWh of heat a year: good for drying grain, wood chip and logs, or heating buildings close by.
