How much is it reasonable to put the price up in winter to cover winter heating?

We are offering a spa pool which has to be heated 24/7

@Colin547 What is reasonable is clearly the cost of the heating spread over a number of nights. What is acceptable will depend on the local market and what guests are willing to pay. At the end of the day if people are not willing to pay what it costs then perhaps you should consider closing the spa pool for the winter months. Alternatively make the spa pool a chargeable extra and only heat it if people want to pay for it.
