The general rule for Al wiring is one gauge size larger than the equivalent for Copper. A typical 20 amp heating circuit would need to have #10 gauge wire in Aluminum, #12 which is smaller, for Cu. The length is directly proportional to the wattage, long baseboard heater, big watts. I would pull new copper 12 ga wire from the panel to the heater locations for safety and peace of mind. Also fire insurance costs less if you can say the wiring is copper. The wiring to the thermostat carries the same current as the baseboard heater, also should be replaced. Or get the new models that have built-in programmable thermostats, just one cable from the panel or junction box. An electrician should do the final work and sign off on it somehow, save the receipt. Jim is correct about the old vs new, but new heaters like new switches and outlets, help to complete a reno. Al wiring should be inspected and have connections redone every 10 years.
